What are some good growing up quotes in 'To Kill a Mockingbird'?

Chapter 1 page 13

Jem thought about it for three days. I suppose he loved honor more then his head, for Dill wore him down easily: "your scare," Dill sai, the first day. "Aint scared, just respectful," Jem said. The next day Dill said, "your too scaredeven to put your big toe in the front yard."

In this passage, Jem is growing up because he never backed down on a dare, he is growing up because he is respecting to not trespassing on the Radleys place.
