"'Remember it’s a sin to kill a mockingbird.' That was the only time I ever heard Atticus say it was a sin to do something, and I asked Miss Maudie about it. 'Your father’s right,' she said. 'Mockingbirds don’t do one thing but make music for us to enjoy . . . but sing their hearts out for us. That’s why it’s a sin to kill a mockingbird.'” -Harper Lee, To Kill a Mockingbird
