Final answer:
He ruined his opportunity with the U.S. president's son due to inappropriate or unprofessional behavior, potentially influenced by his background or differing philosophies. The situation mirrors internal conflicts faced by those from humble beginnings in professional settings.
Step-by-step explanation:
When he had the opportunity to meet with the U.S. president's son and acquire a job working for the president, he ruined his opportunity because he exhibited a behavior that was inappropriate or unprofessional. This scenario does not provide the specific reason he ruined the opportunity, but the behavior could have been influenced by his background, as indicated by his deference towards the wealthy, or by his philosophy differing from that which was required by the presidency. Additionally, his actions might reflect a breach of his own ethical or moral code, as suggested by the phrase defying the laws, which figuratively nurtured him.
Such a complex situation can also relate to the psychological struggle of individuals who come from a humble background, such as the father described as a former soldier and poor planter, and their interactions with figures of higher societal status. This internal conflict could manifest in behavior that undermines their professional interactions, similarly to how Kim's failure in his history course was a result of his own actions, yet he blamed external factors.
