In the book To Kill A Mockingbird by Harper Lee, what of some examples of Atticus Finch being patient?

Atticus is unfailingly patient. When Scout begins to use obscene language in the hopes that he'll realize that she's learning it at school and thus will let her stop going to school, he ignores it and explains to Uncle Jack, "Don't pay any attention to her, Jack.

Atticus is unfailingly patient. When Scout begins to use obscene language in the hopes that he'll realize that she's learning it at school and thus will let her stop going to school, he ignores it and explains to Uncle Jack, "Don't pay any attention to her, Jack. She's trying you out. Cal says she's been cussing fluently for a week, now." He suspects (and it probably right) that it's a phase she's going through and/or she's just trying to get attention, and when she figures out that it doesn't work, she'll stop. 

When Mrs. Dubose accuses Atticus of "lawin' for niggers and trash" to Jem and Scout (and Jem destroys her camellias), Atticus says to Jem, "I have no doubt that you've been annoyed by your contemporaries about me lawing for niggers, as you say, but do something like this to a sick old lady is inexcusable." No matter what people say about him, Atticus keeps his head. 

After the trial, when Mr. Ewell spits on Atticus in public and says, "Too proud to fight, you nigger-lovin' bastard?", Atticus merely responds, "No, too old." No matter what happens, it seems, Atticus is patient and collected.
