Must be accepting of others' shortcomings. From Scout's perspective, all people, regardless of their station in life, are held to the same standards. Consequently, she feels perfectly justified in commenting on Walter Cunningham's table manners. Calpurnia takes her to task saying, "'Don't matter who they are, anybody sets foot in this house's yo' comp'ny, and don't you let me catch you remarkin' on their ways like you was so high and mighty!'" Adding insult to injury, Atticus agrees with Calpurnia.
Interestingly, in spite of Scout's protests that Walter Cunningham "made me start off on the wrong foot," her friendship with him will later save Atticus in a potentially life-threatening situation.
The art of compromise. Despite Atticus' probing questions about Scout's first day of school, she says little. Scout is despondent at the thought of not being able to read at home anymore, but reluctant to tell Atticus after the trouble she's been in all day. Atticus is quite understanding and suggests a compromise: "'If you'll concede the necessity of going to school, we'll go on reading every night just as we always have.'" Surprisingly, Atticus asks that she keep their deal a secret from Miss Caroline, introducing Scout to the idea of a white lie. Throughout the story, Atticus functions as a peacemaker. Lee gives the reader a first glimpse into Atticus' reasoning abilities and personal beliefs in his choice to compromise with Scout rather than confront or ignore Miss Caroline.
