Atticus maxim which he tries to teach the children. By the end of the book, Scout has learnt her lesson as she stands from the Radley Porch and is metaphorically and literally seeing Maycomb from Boo's perspective.
Dill and Jem start to become best friends and scout feels left out. She quickly becomes good friends with a neighbor who is he widow. A garden and bake together. She says that the boo Radley was a nice boy when he was younger. Dill and jem decided to invite boo to go and get ice cream with them. Atticus catches them and tells them to stop playing the game with the boo Radley in it and not to give him any notes because it will make him mad.
This quote is in reference to Scout finally meeting Boo Radley at the end of the book. This scene was actually near the beginning of the book when at bedtime Scout asked what Atticus will leave her if his pocket watch is to be Jem's?
