Atticus treats Walter with respect when he comes to visit the Finch home. Walter's family is poor and Walter has had to stay out of school for long periods to help his family survive. Atticus listens carefully, and the man and boy "talk like two men."
Atticus, along with Calpurnia, continue to show their guest respect. In Scout's opinion, Walter breaks the standard rules of decorum when he asks for molasses (a treat) and then pours more than is polite all over his food: "He would probably have poured it into his milk glass had I not asked him what the sam hill he was doing," Scout exclaims.
Atticus and Calpurnia will not allow such a dressing down to company. Scout is quickly chastised for her lack of manners. Atticus extends the hand of humanity and human dignity to everyone.
