In the morning, everyone's appetite was "delicate" except for Jem's. That means that Atticus did not eat much, probably from a nervous stomach. He admires the fact that his son can eat so much. He defends Calpernia's right to know what is going on in the household -- which shows his attitude toward black Americans. They had trouble the night before, a hanging mob had tried to get ahold of Tom Robinson before the trial. Atticus anticipates trouble again. Before he leaves for the courthouse, Atticus tells Jem and Scout not to go downtown to the courthouse. He wants to keep them safe.
