Final answer:
The question pertains to why a character, Mom, doesn't want to talk about money. The provided narratives suggest possible themes of avoidance, embarrassment, and the emotional weight of financial discussions.
Step-by-step explanation:
The question seems to be related to a character named Mom not willing to engage in a conversation about money with a character named Walter. Without specific context, it's challenging to provide direct phrases that explain the reasoning behind Mom's hesitation; however, the various narratives provided suggest different themes such as reluctance to face reality, fear of revealing true financial circumstances, or possibly protecting a family member from distressing truths. In each scenario, characters grapple with dilemma, pride, secrecy, or fear, causing them to avoid candid discussions about monetary issues.
For example, in the narrative involving Mr. McTeague, there is a sense of embarrassment about not having enough money, which inevitably leads to avoidance. Similarly, Trina's reluctance to spend her winnings and her family's argument over how to use the money suggest the emotional weight that financial decisions can carry. This can be associated with reasons why someone might avoid discussing money, focusing on the psychological and emotional factors over the rational or practical.
