It was then, I suppose, that Jem and I first began to part company. Sometimes I did not understand him, but my periods of bewilderment were short-lived. This was beyond me.

– Harper Lee

To Kill a Mockingbird, Chapter 6. Jem wants to go back at night to the Radley house to retrieve the pants he lost there, because he doesn’t want Atticus to find out he was there. Scout doesn’t want him to go because she thinks that Nathan Radley will shoot him. Scout realizes that Jem is getting older, and she is too young to really understand him.
