What does the discussion between Atticus and Scout in chapter 3 suggest about their relationship?

In Chapter 3, Atticus's patient teaching gives Scout a lesson that he says will help her "get along better with all kinds of folk": she has to remember to judge people on their intentions rather than their actions, and put herself into the other person's shoes in order to understand them best. The chapter establishes that Atticus can relate to all kinds of people, including poor farm children. He talks to his daughter like she's a young adult rather than a little girl, which shows that he respects her ability to be perceptive, and also shows his confidence in her feelings for his opinions.
