Describe the situation with Walter Cunningham. What does this say about Scout’s character? What about the Cunninghams?

Scout got in trouble for explaining why Walter couldn't borrow a quarter to buy lunch. Scout blamed Walter for her getting in trouble so she rubbed his nose in the dirt until Jem stopped her and invited Walter to dinner. This shows Scout to be feisty as well as valuing school. She can also be impulsive. Walter is proud but poor. He refuses to take a "loan" from his teacher. Walter, however, is not up to the task of fighting Scout. After Jem invites Walter to lunch, we see a bit more of Walter and Scout's reaction to him.
