3 main ideas for chapter 4

School continues; the year goes by. Scout doubts that the new educational system is really doing her any good - she finds school boring and wishes the teacher would allow her to read and write, rather than ask the children to do silly activities.

One afternoon, as she runs past the Radley house, she notices something in the knot-hole of one of the oak trees in the front yard. She investigates further and finds two pieces of chewing gum. More gifts show up in the knot hole.

One day Atticus catches them playing the game and asks them if it has anything to do with the Radley family. They deny it, and Atticus replies, "I hope it doesn't." Atticus's sternness forces them to stop playing, and Scout is relieved because she's worried for another reason: she thought she heard the sound of someone laughing inside the Radley house when her tire rolled into their yard.
