In Chapter 13, what is Atticus' dilemma regarding his children?

In Chapter 13, Aunt Alexandra moves into the Finch residence so that she can be a positive female role-model for Scout. Aunt Alexandra is the prototypical "Southern Bell," who has a fascination with family backgrounds and heredity. She becomes upset with Atticus because he hasn't taught his children about the Finch family history. Aunt Alexandra tells Atticus that he should instill a sense of family pride in his children. Atticus attempts to lecture Scout and Jem about their rich family history but feels ridiculous doing so. He tries to tell his children to act like little ladies and gentlemen. Scout begins to cry because she senses that her father is not acting like himself. Eventually, Atticus tells them not worry about it, and they don't need to remember everything the Finches did.
