After my bout with Cecil Jacobs when I committed myself to a policy of cowardice, word got around that Scout Finch wouldn’t fight any more, her daddy wouldn’t let her. This was not entirely correct: I wouldn’t fight publicly for Atticus, but the family was private ground. I would fight anyone from a third cousin upwards tooth and nail. Francis Hancock, for example, knew that.

To Kill a Mockingbird, Chapter 10. After Atticus urges her to use her head instead of her fists, Scout follows a “policy of cowardice” in which she will not retaliate against others. Scout wants to fight with Cecil Jacobs because he announced that “Scout Finch’s daddy defended n*****s.” But she doesn’t because it would let Atticus down.
