Atticus Finch: There are some things that you're not old enough to understand just yet. There's been some high talk around town to the effect that I shouldn't do much about defending this man.
Scout: If you shouldn't be defending him, then why are you doing it?
Atticus Finch: For a number of reasons. The main one is that if I didn't, I couldn't hold my head up in town. I couldn't even tell you or Jem not to do somethin' again.
[he puts his arm around her]
Atticus Finch: You're gonna hear some ugly talk about this in school. But I want you to promise me one thing: That you won't get into fights over it, no matter what they say to you.
