Final answer:
Without the context of the story 'Us and Them', it's impossible to determine why the narrator behaves a certain way when asked to bring down candy. Character behavior is influenced by motivations and context within the narrative.
Step-by-step explanation:
The specific details of the narrator's actions when asked by his mother to bring down his candy are not provided in the excerpts given. Generally, the behavior of a character in a narrative can be shaped by various motivations such as guilt, fear, defiance, or a desire to protect something they value.
The narrator's reasons for acting the way they do would be influenced by the context of the story and their personal characteristics.
In the story 'Us and Them', when the narrator's mother tells him to bring down his candy, he hesitates and ultimately refuses to share it with his family.
He behaves this way because he wants to keep the candy to himself and enjoy it alone. This behavior is influenced by the narrator's desire for control and a sense of ownership over something in his life.
