How does Kreb's mother embody the community's values? what does Kreb think of those values?

Krebs's mother has very conventional ideas about her son's maturation, and she is completely oblivious to what Krebs has seen and experienced in the war. She and Krebs's father have agreed that Krebs should be allowed to take the family car out at night, which seems a bit ludicrous. He is, readers understand, a man at this point, but his parents are still treating him as if he is a teenager.
Krebs's mother is a reflection of community values that cast men in the role of breadwinners, women in the role of stay-at-home mothers, and children as dependents who live with their parents until they marry and move out of the family home. She is also the keeper of the faith, and she tells Krebs that he must do the work that God wants him to do.
Krebs does not share his mother's values. He has renounced his faith in God, and the implication is that his war experiences have seriously eroded his faith. He does not want to take the family car out at night, and he is uninterested in being married off to a girl in town. He is living inside his head and questioning everything he accepted at face value before he went abroad.
