What is an example of how Scout matures in part 1 of To Kill a Mockingbird?

Scout shows maturity when she speaks with Atticus about his defense of Tom Robinson in chapter 9, and she uses what she has learned from her father the next day when she resists fighting with Cecil Jacobs.
At school one day, Cecil tries to pick a fight with Scout, saying that her father defends "n——s." Scout gets angry and tells Atticus about the incident, and he talks with her about the importance of doing his best to defend an innocent man like Tom. He doesn't actually think he will win the case, but sometimes winning doesn't matter, and besides, even if people in Maycomb disagree with what he is doing to defend Tom, Maycomb is still their home, and they must stay friends with everyone.
Scout takes this lesson to heart, so the next day at school, when Cecil taunts her again, she walks away. This action shows great maturity as Scout usually gives in to her temper.
