What does Atticus want Scout to understand about Miss Caroline?

In Chapter 3, Scout returns from a rough first day at school. She sits down to read with Atticus and tells him that she doesn't think she'll go to school anymore if it's okay with him. Scout explains the unfortunate events that took place throughout the day to her father. Miss Caroline, who is new to Maycomb, punished Scout following her failed attempt to explain Walter Cunningham's "family ways." Atticus teaches Scout a "trick." Atticus tells Scout to metaphorically "climb into another person's skin" and walk around in it. He explains to her that she learned a lot of things about Miss Caroline during the first day of school. He tells Scout that she shouldn't expect Miss Caroline to understand everything about Maycomb and its community in one day. He wants Scout to understand that Miss Caroline viewed the situation differently and wants her to look at the situation from Miss Caroline's point of view. This is an important lesson in Scout's moral development throughout the novel.
