In Ian McEwan's novel, "Atonement," the protagonist Emily reflects on her parents' beliefs, stating that they thought hot weather led to misguided behavior in youth. This perspective highlights the influence parental views can have on shaping a child's understanding of morality and social conduct. It suggests a time when strict societal expectations were prevalent, and young people's actions were often scrutinized.

Emily's remark indicates a broader commentary on the relationship between environment and behavior. The heat symbolizes not only the physical discomfort but also the emotional and moral turmoil that can arise in such conditions. The contrast between personal feelings and societal expectations sets the stage for conflict, emphasizing the complex dynamics at play in the characters' lives.
