Finance for Behavioural and Asymmetric Composition-myassignmenthelp

Question: Discuss about theFinance for Behavioural and Asymmetric Composition. Answer: Evaluating the occurrence of short run IPO under-pricing in Australia and US by contrasting the results with empirical study conducted on Hong Kong: The theories comprising of behavioural and asymmetric composition can be identified, as the measure fulfilling the viability of IPO under-pricing in US and Australian market. Moreover, the asymmetric theory indicates that information distribution is not adequately conducted among investors and companies, as it allows the investor to gain abnormal gains. Moreover, the behavioural theory indicates the willingness of the investor to investment in a stock during their IPOs. Hence, the combination of both asymmetric and behavioural theory directly supports that presence of IPO under-pricing, as it allows the investor to generate high rate of return from investment. The investors with the right information forces the price of IPO down to maximise the returns that is generated from investment. Hence, it could be understood that both asymmetric and behavioural theory supports the presence of under-pricing of IPO shares in US and Australian stock market. The empirical research mainly focuses on determining the overall under-pricing of initial public offerings which is been conducted in Hong Kong stock market. The research paper uses the overall duration of 10 years to identify the implications and impact of under-pricing on initial public offerings, while detecting its presence in the Hong Kong stock market. Identifying the presence of under-pricing measure used in Hong Kong stock market could relevantly help in understanding its presence in Australian and US stock market (Chong, Yuan and Yan 2010). The research estimates the average IPOs and pricing level in Hong Kong stock market to detect presence of under-pricing in the stock market. In this context, Boulton, Smart and Zutter (2017) stated that with the under-pricing of IPOs the underwriter is able to attract more investors during the IPO initiation and effectively free float shares of the organisation. From the early valuation of the research it could be identified that 16.6% of the 92 IPOs were on an average underpriced, directly indicate its presence in the Hong Kong stock market. Moreover, Beck (2017) stated that the IPO under-pricing is a relatively high in developing countries in comparison to developed countries, as investors are keen on increasing the profits from the initial public offering. The researcher also evaluated the short run abnormal returns that are generated from the IPO under-pricing in Hong Kong stock market. This would eventually help in satisfying the statement regarding the presence of under-pricing of IPOs. The researcher collectively uses dependent variables such as the closing price of IPOs first day trading, which is used in understanding the difference between the initial price and the closing price of a particular stock (Chong, Yuan and Yan 2010). Second dependent is also used in the research, which comprises of data from first 7 trading days and firs t 15 trading days for detecting the overall presence of under-pricing in IPOs. The explanatory variables are also used in the research for identifying the impact of under-pricing in determining the overall share price of IPOs. With the use of geometric mean the overall returns and annual growth of a particular stock can be identified, which might allow investors to increase the level of returns from investment. The researcher has a relatively used regression analysis to identify the significance of the values derived from the calculation. The researcher also evaluates that the Four Big Firms conducts the IPO valuation and selling in the stock market. The calculations mainly state that IPO selling conducted by PricewaterhouseCoopers and KPMG is much accurate on Hong Kong, as compared to the evaluations conducted by Ernst Young and Deloitte Touche (Chong, Yuan and Yan 2010). The empirical research also indicated that there is a presence of under-pricing of IPL during the initial stage, where low price shares are provided to investors to complete the share selli ng process. The low cost shares provided to investors relatively allows the company to sell of their issues for generating the required level of capital (Francis 2017). From the overall evaluation, it could be identified that IPO under-pricing level in Hong Kong stock market is at the levels of 16.8%, which has a relatively small magnitude of an uprising in comparison to other countries (Chong, Yuan and Yan 2010). Moreover, the shares related to A-Category are less impacted with the under-pricing process, while the B-Category stock is highly impacted by the under-pricing process. Therefore, from the evaluation of the empirical research it could be understood that developed countries have less impact of under-pricing during initial public offerings as compared to developing countries. However, the presence of enterprising for short duration is the relatively present in the Hong Kong stock market as evaluated from the empirical research. Hence, from the valuation of Hong Kong stock market it could be identified that both US and Australian stock market conduct IPO under-pricing for short duration. Consequently, the occurrence of short-run IP on the pricing in the Australian market would eventually hamper the company's ability to raise the level of capital to support its operational plans. This under-pricing is essential for both the investors and companies to benefit from the initial investment conducted during the IPO session (Morricone et al. 2017). The research directly shows that in case of developed countries, the under-pricing impact is less, while developing countries have high impact of short run under-pricing in its stock market, which benefits the initial investors and allow them to generate higher returns from investment.

the chrysalids Essay Example

the chrysalids Essay the chrysalids BY ntul 23gi11123 The Chrysalids society and our modern society is very similar because both societies are Judged how people look but a difference is how religion plays role in daily life, and that modern society is still accepting compared to the Chrysalids society. The appearance of a human in both societies is very big. People even in modern society are called bunch of names still, for example someone with braces or glasses are always teased. In the Chrysalids society this would be known as a blasphemy against the true image of god, and hateful in the sight of god. 13) This meant that anyone that was not human like was killed (deviants). This also referred to plants and animals. The cause of deviation in the Chyrsalids society is because of the radiation from a nuclear war. The Chrysalids religion compared to modern societys religion is very different. The Chrysalids society only thought in one perspective and one belief, whereas now in modern society there are so m any perspectives and beliefs. For example Sophie is a girl David met who has six toes, and if anyone found out she would be killed. Sophie pleaded for her life the day David saw the extra toe, as she said you mustnt ever tell, never, never! Promise? (9) Luckily David is also a deviant and kept her secret. With this perspective and belief, the Waknuk society had an impact on controlling peoples actions that caused isolation and most people didnt understand of situations like this at all. A big difference in modern society compared to the Chrysalids society is that modern society still accepts. If somebody was to have a disease or physical appearance problem, modern society would help them and ssist with that whereas in the Chrysalids society you would be killed.

He believed that this cat was a deviant so he got a warrant for it and killed it. Soon after he found out that the Dakers cat was a recognized breed of tailless cats with a well-authenticated history (37) This shows how strict they were on appearance. The societys are similar in some ways because there is still rejection of appearance but differs because how religion is practised and also that modern society still welcomes everyone and isnt killed.

Ontario Harmonized Sales Tax (HST)

Ontario Harmonized Sales Tax (HST) What is the Ontario Harmonized Sales Tax? As part of its 2009 provincial budget, the Ontario government tabled a bill on November 16, 2009 to introduce a harmonized sales tax (HST) in Ontario. The harmonized sales tax being proposed by Ontario will combine the eight percent provincial sales tax with the five percent federal goods and services tax (GST) to create a single 13 percent harmonized sales tax (HST) administered by the federal government. The Ontario HST is scheduled to take effect July 1, 2010. Why is Ontario Switching to the HST? The Ontario government says Ontarios current dual tax system puts Ontario businesses at a competitive disadvantage and implementation of a single sales tax would bring the province into line with the most efficient form of sales taxation around the world. They say the tax reform being proposed, including the HST, will create jobs and position the Ontario economy for future growth as the province emerges from the economic downturn. They also claim the single sales tax will reduce paperwork costs for business by more than $500 million a year. Tax Relief to Offset the Ontario HST The 2009 Ontario budget will provide $10.6 billion over three years in personal income tax relief to help consumers through the transition to the single sales tax. This includes personal Ontario income tax cuts and direct payments or rebates. It will also provide $4.5 billion in business tax relief over three years, including reducing the corporate income tax rate to 10 percent over three years, cutting the small business tax rate and exempting more small and medium-sized businesses from corporate minimum tax. What the Ontario HST Means to Consumers For the most part, consumers will not notice a large change in prices. However, there are many items currently exempt from the provincial sales tax that will no longer be exempt. They include: gasolineheating fuelselectricitytobaccopersonal services, such as haircuts, membership fees for clubs and gyms, magazines, taxi fares, professional services for lawyers, architects, and accountants, and real estate commissions. The HST will not be charged on: basic groceriesprescription drugssome medical devicesmunicipal public transithealth and education serviceslegal aidmost financial serviceschild caretutoringmusic lessonsresidential rentscondo fees    Currently, the PST is not applied to those items. There will still be a few exemptions from the provincial portion of the sales tax: childrens clothing and footweardiaperschildrens car seats and car booster seatsfeminine hygiene productsbooks (including audio books)prepared food and beverages sold for $4.00 or lessprint newspapers The Ontario HST and Housing No HST will be charged on residential rentscondo feespurchase of resale homes    The HST will be applied on the purchase of new homes. However, homebuyers will be able to claim a rebate of some of the provincial portion of the tax for new homes priced up to $500,000. The rebate for new primary residences under $400,000 will be six percent of the purchase price (or 75 percent of the provincial portion of the tax), with the rebate amount reduced for homes priced between $400,000 and $500,000. Buyers of new residential rental properties will receive a similar rebate. The HST will apply to ​real estate commissions.

This involves having the mandate of monitoring contractual performance based on giving briefs about presentations at the end of every contract. Additionally, the officer serves as the technical liaison whenever there are contracting and procurement challenges. Furthermore, this officer also overlooks at the communication channel by addressing issues of technical contacts and regulations that govern contacts (Bastianelli et al, 2003). Therefore, before this research delves into the effectiveness of contract office, there is the need to explore the background. Background In most na tions, the effective management of performance of contracts is paramount to ensure the integrity of contracts and related programs. Therefore, most government offices decided to create the contracting office under the leadership of a contracting officer representative. There was also the need to ensure that procurement and acquisition among employees was upgraded for the benefit of timeliness, completeness and quality. On that account, the government defined contracting as the primary technique that Federal Government agencies utilize in the buying of products or services from other agencies outside the government (Cibinic et al, 2006). Similarly, the government set the Federal Acquisition Regulation (FAR) as the official regulatory body of managing contracts. As a result, the FAR came as a body that offers quality products and services to its clients while preserving the public’s trust and meeting their policy objectives. In addition, because of the creation of the office, t he contracting office representative assumed responsibility for contracting for purchase, the acquisition of products and services from the entities of the public sector, federal agencies, and local and state government companies (Kelleher et al, 2010). Statement of the Problem The challenge of whether the contracting officer in the federal representative is effective is determined by several factors. For example, there is a need to consider the stipulated roles and responsibilities of the contracting officer. Therefore, the jurisdiction of the federal office in terms of making purchases of products and services should meet the standards of performance contracts. These performance contracts should be targeted at private sectors, local and state entities that measure their contracts through the parameters of the job description. Similarly, the federal agency should make clear definition of the contractual terms that

Corrosion Properties of Al-B4C Composites

Corrosion Properties of Al-B4C Composites Abstract[SM1] The influences of adding B4C particles on corrosion behavior of Al-2wt.% Cu alloy was studied in 3.5 wt.% NaCl solution at room temperature using linear and cyclic polarization, immersion test and Electrochemical Impedance Spectroscopy (EIS).[SM2] Nano-composites reinforced with 2, 4 and 6 wt. % B4C were produced through mechanical milling and tested to explore the B4C contents effects on the corrosion properties. [SM3]Influences of the grain size were also studied comparing the coarse-grained and milled Al matrix. Results revealed that the corrosion resistance of Al matrix decreases by reducing the particle size. Sample with 2wt.% B4C showed best corrosion resistance amongst all. Key words: Mechanical milling, Nano-composite, Al, B4C, Corrosion Introduction Metal Matrix Composites were remained the focus of attentions in aerospace, automotive and military industries in recent years. These materials offer several advantages including the high strength to weight ratio, excellent wear resistance and high stiffness compared to the original alloys. The commonly used reinforcing materials are; silicon carbide, aluminum oxide and boron carbide. Due to density differences between the reinforcements and the matrix materials, segregation has been found to be a major problem in producing metal matrix composites. Ball milling is considered to be an important technique for producing nano-crystalline composites. Growing interest for this technique is due to preparing materials with unique chemical, physical and mechanical properties. Ball milling process makes uniform distribution of reinforcement particles in the matrix, preventing the segregation which is commonly found in composites fabricated through other methods [1-4]. Effects of B4C particles as reinforcement materials on mechanical properties of aluminum base alloys are existed in the literatures, but studies on corrosion behavior for these composites are rarely reported. Corrosion behavior is a key parameter for assessing the applications of composites in marine environments. All in all, incorporation of the reinforcements into Al alloys increases the corrosion rate of composites in comparison with matrix. Primary corrosion initiation sites in MMCs[SM4] are dependent on electrical conductivity of reinforcement material, reinforcement volume fraction, intermetallic phases and corrosive environment. Grain size has also a major effect on corrosion behavior of the composites [5-9]. Present research aims at studying the corrosion properties of Al-B4C composites. The influence of different B4C contents on corrosion behavior of Al matrix composites was investigated. Coarse-grained Al matrix was also used to explore the effect of grain size on corrosion resistance. Experimental Al–2wt.% Cu and the nano-sized B4C particles were respectively used as matrix and reinforcements in fabricating the specimens. Besides a plain matrix sample, others were synthesized through mechanical alloying of the powder mixtures with 2, 4, and 6 wt.% of B4C. Ball milling was done by a planetary mill, equipped with two tempered steel vials containing Chrome steel balls (φ=20mm). The rotational speed and the ball to powder weight ratio were set at 300 rpm and 10:1, respectively. Milling process was performed at room temperature under argon gas (99.999%) atmosphere protection for 20h[SM5] to achieve steady state condition. Mechanically milled powders were then cold pressed and hot extruded with an extrusion ratio of 10:1 at 550à ¢- ¦C. Reference Al alloy sample was prepared from unmilled aluminum powder using similar pressing and extrusion processes. Electrochemical measurements including linear polarization, cyclic polarization, weight loss and electrochemical impedance spectroscopy tests were applied to 3.5wt.% NaCl solution at room temperature. Three electrodes system, including a working electrode, a platinum counter electrode and a silver-silver chloride electrode (Ag/AgCl) as [SM6]reference electrode were used. The exposed area of samples was polished to 1200 emery paper. Tafel tests were performed at a scan rate of 1 mV/s, from -2000mV to 500mV using a 273A Princeton Applied Research EGG model potentiostat/Galvanostat. Cyclic polarization measurements were carried out under conditions similar to Tafel test. After reaching to the 500mV point, scan direction was reversed. In order to find out the exact protection potential, scan rate of 0.5 mV/s was applied in reverse direction. Disc shape specimens (10mm in diameter and 3mm thick) were immersed in 3.5wt.% NaCl solution in atmosphere for 1, 3, 7, 14 and 28 days. Corroded samples were cleaned according to G1 standard, [SM7]dried and weighed before and after the experiments using a balance (H- Z- K 210 model) with an accuracy of 0.00001 g. The mass losses for samples were finally measured by considering their total surface area. Phase characterization of specimens before and after the immersion were carried out through [SM8]X-ray diffraction (XRD) [SM9]technique on a Phillips X‘Pert Pro diffractometer using monochromatic Cu-KÃŽ ± radiation. Morphology and chemical analysis of samples were also characterized using scanning electron microscopy[SM10] (SEM), SU8040model, equipped with an energy dispersive spectrometer [SM11](EDS). Electrochemical impedance spectroscopy[SM12] (EIS) measurements were done with a frequency ranging from 10 mHz[SM13] to 100 MHz. The results were analyzed by means of Zview2 software. Result and Discussion- The milling part Fig 1 shows the morphology of Al/Cu alloy and the Al/Cu-4wt.% B4C composite after 20 h[SM14] of mechanical milling. By increasing [SM15]milling time, the particle size decreases besides narrower size distributions.[SM16] The nearly equiaxed crystal morphology of particles suggests that, the 20 h[SM17] of milling time was sufficient to reach desired steady-state condition. Results in table 1 demonstrate[SM18] that by increasing the B4C contents, the average particle size decreases. Table 1 shows the influence of B4C content on the crystallite size and the lattice strain of aluminum matrix, according to Williamson–Hall method. As expected, the mechanical milling induced severe plastic deformation, leading to the formation of nano-crystalline metal matrix. The crystallite sizes varied with B4[SM19]C contents, showing the effect of hard particles on grain refining performance of metal matrix[SM20]. It is known that the milling stages introduce plastic deformation of ductile matrix, micro-welding, and the fracture of deformed particles in metal matrix [10, 11]. As compared to mechanical milling of soft powders, the presence of hard particles causes an increase in local deformation of matrix around reinforcement particles, which indeed would enhance the work-hardening rate of metal matrix. Additionally, fracture toughness of composite powders is lower than that of the matrix material [11]. On the other hand, an increase in the content of particles results in more frequent interactions between the dislocations and the hard particles [12], which accelerating the onset of mechanical-milling stage, and contributing to grain-refinement process [11].[SM21] Microstructural examination of as-cast composites revealed that the B4C particles were not distributed uniformly in the matrix and the regional clusters of particles existed. Since the wetting by molten matrix was poor, a uniform distribution of particles could not be observed in composites fabricated by stir casting. In addition, other factors like stirring speed, pouring condition, solidification rate, etc. [SM22]have also had a noticeable influence on particles distribution. In extruded samples, a more even distribution of B4[SM23]C can be observed. Fig. 2 shows the back-scattered electron SEM micrographs of extruded composites used in this study. A uniform distribution of ceramic reinforcements is evident in both composites. In addition, there are no traces of voids in the microstructure which in turn suggests that there was full-densification of composite upon extrusion.[SM24] Result and Discussion- The corrosion part Potentiodynamic Polarization Tests The Potentiodynamic Polarization behaviors of different samples in 3.5 wt% NaCl solutions after 1 hour of testing are given in Fig. 3. Their Ecorr, icorr and ipassive values (obtained from Tafel-type fit) are summarized in Table2[SM25]. Data shows that Al-cast has a lower corrosion rate than Al-milled. As the milled alloy has finer grains, it was expected to be less corrosion resistant because of having more grain boundaries, means higher susceptibility to electrochemical reactions and hence to corrosion. [SM26]It can also be seen that the characteristics of polarization curves for B4C composite samples are quite similar to base the alloy[SM27], indicating that the reactions are similar for both. According to table 2, adding 2wt.% B4C to the base material lowered the corrosion rate slightly, because the ceramic particles may to some extent hindered electrochemical dissolution physically. On the other hand, adding more B4C particle to the composite increases the corrosion rate. In any Al alloy-B4C composites, forming intermetallic compounds plays an important role in any chemical and electrochemical reactions that take place on composite surface in a corrosive environment. Fig.[SM28] 4 shows the X-ray diffraction pattern for Al 6wt.% B4C composite. It can be seen that other than Al matrix, there would be considerable amounts of Al3BC species which were produced when the Al reacted with B4C particles. As Al is more anodic with respect to intermetallic, having more of B4C in matrix dominates the effect of physical blocking of electrochemical reactions for ceramic particles in the solution and corrosion rate increases. Therefore [SM29]other than general corrosion of the matrix, there will be galvanic corrosion between the matrix and intermetallic resulting localized corrosion (pitting) on composite surface. In Al 6wt.% B4C sample, the corrosion rate decreased. This can be explained through passivation point of view as shown in polarization curves in which, the passive current density increases by increasing the B4C content. This may be caused by the formation of more porous and unstable passive layers produced by higher intermetallic particles and also leading to more susceptibility to localized corrosion.[SM30] Weight Loss Measurements Figure 5 represents the weight losses for different samples at different immersion times. Diagram demonstrates that the Al cast has the lowest weight loss, therefore [SM31]the lowest corrosion rate of all samples. B4C composites show higher corrosion rates than Al-milled suggesting that adding B4C to samples increases the corrosion rate.[SM32] As mentioned above, adding B4C to the alloy produces Al3BC intermetallic during corrosion.SEM micrographs of the Al 6wt.% B4C before and after the immersion for 28 days [SM33]are shown in Fig[SM34] 6. Al matrix and Al3BC intermetallic are pointed out in Fig. [SM35]6. EDX analysis results of the intermetallic phase from Figure 4-b is also demonstrated in Fig.[SM36] 7. It reveals that, considerable amounts of the compound exist in the matrix [SM37]which agrees with the XRD results discussed before. Finally, it is observed that the results from immersion and polarization tests are in agreement with each other. It is indicating that besides a general corrosion, there is a galvanic corrosion between the matrix and the particles leading to localized corrosion. Cyclic Polarization Studies: Characteristic potential values such as:[SM38] pitting potential (Epit), corrosion potential (Ecor), and re-passivation potential (Erp) were determined through cyclic polarization studies. As it is observed in Fig[SM39] 8, the nature of potentiodynamic polarization curves in the 3.5% NaCl solution reveals typical characteristics of the material undergoing spontaneous passivation. Reverse scan shows a hysteresis cycle, showing the characteristics of pitting. After reaching to a maximum level, the current begins to decay without any oscillation. Following a linear current-potential relationship is suggesting that an ohmic controlled process was taking place [12-15]. Additional electrochemical parameters given in the table [SM40]are: à °Ã‚ Ã¢â‚¬ ºÃ‚ ¥Epit=Epit-Ecorr, à °Ã‚ Ã¢â‚¬ ºÃ‚ ¥Erp=Epit-Erp. à °Ã‚ Ã¢â‚¬ ºÃ‚ ¥Epit is a measure of the width of passive region on polarization curve, indicating the susceptibility to pitting. à °Ã‚ Ã¢â‚¬ ºÃ‚ ¥Erp is used to assess the repassivation behaviour of propagating pits and hence, the ease with which locally active sites can be eliminated.[SM41] à °Ã‚ Ã¢â‚¬ ºÃ‚ ¥Eprotection represents Erp-Ecorr and indicates the protected region. Pits are formed in this region, repassivation and larger region means more resistance to pitting for composite. [SM42]According to table[SM43] 3, the largest protection region was belonged to Al cast. Milled sample showed a smaller region and because of having more grain boundaries on the surface, by creating smaller nucleation sites for pits, made the sample more prone to pitting. [SM44]Adding B4C to samples confines the region and lowered[SM45] the resistance to pitting corrosion. EIS Studies In order to study the corrosion behavior of B4C composites and the base alloy, EIS measurements were carried out for all specimens at their Ecorr in 3.5% NaCl solution. Figure 9 shows results in the form of nyquist[SM46] diagrams. There is a common characteristic for all curves, i.e. a capacitive semicircle in the high frequency ranges. High frequency capacity loop was mainly related to the characteristics of electrical double layer formed at the interface between the adsorption layer on [SM47]metal surface and the electrolyte [12]. The biggest semicircle was noticed for the Al cast sample, indicating that the alloy has the highest resistance to corrosion. Al-BM sample has an additional semicircle in low frequency range, which may be related to the charge transfer across the metal-electrolyte interface. Another noticeable point is that, inductive loop [SM48]is related to the salt layer formation on the surface. It may also demonstrate that, [SM49]adsorption of an anion like chloride which is presented in electrolyte,[SM50] caused the pitting corrosion. Al-BM also has[SM51] lower resistance to corrosion than Al-Cast. Corrosion resistance for Al 4%B4C sample was higher than the Al-BM. But for the 2% and 6% composites, there were less improvement observed [SM52][16, 17]. Conclusion Results from electrochemical measurements which were carried out on Cast and Milled alloys and the B4C composites[SM53] showed that,[SM54] adding B4C particles to milled alloys will not [SM55]change the corrosion resistance considerably. From corrosion resistance point of view, it would be fair to say that the best sample was[SM56] the Al 2%B4C.

Nathaniel Hawthorne points out that the former is true of all people in the novel The Scarlet Letter. In this novel, there are three main characters who commit evil and sinful acts, but each act is at a different degree of sinfulness (i.e. the sins get worse as the story goes a-long). These three sinners, in the eyes of the Puritan community, are the beautiful Hester Prynne, the esteemed Reverend Arthur Dimmesdale, and the cold-hearted doctor, Roger Chillingworth. Like Hawthorne, I believe that evil is the nature of man but that there are different magnitudes of evil; some choose to fight it, like Hester, and some choose to give in, like Chillingworth. Hester Prynne, a strong willed and brave woman, in respect to the two additional people, has committed the least amount of sin in the novel. In the eyes of the Puritan community, though, she has committed one of the worst possible sins that can be imagined: adultery. They feel she is horrendously corrupt, yet it is not truly her fault. Hester is the victim of her husband, Roger Chillingworth's (formerly Roger Prynne) stupidity by sending her to New England by herself, while he remained in Europe. Chillingworth even admitted that it was his fault when he voiced, "It was my folly! I have said it. But, up to that epoch of my life, I have lived in vain."(Ch.4, p. 68) Hester is also a victim of fate. She has no way of knowing if Chillingworth is dead or alive when the Indians capture him after he arrived in North America. She still goes against the strict Puritan rules, and breaks Commandment 7, which was often punished by death. Arthur Dimmesdale is a strong pillar of the community and a very devoted Puritan. What could he do that is worse than young Hester Prynne's appalling act of adultery? Well he goes a little further into the same sin. First of all, he commits adultery with the abandoned Hester. Then instead of admitting his sin to the public, he keeps his dark secret in his heart, knowing it will eat at him for the rest of his life until he reveals it.
