What does Calpurnia’s treatment of Scout reveal about their relationship? Considering the setting of the novel, what is unusual about Calpurnia’s role in the Finch household?

Calpurnia is very much a mother figure to Scout. She not only nurtures her, in her own way, she also disciplines her. Calpurnia very much cares about the person Scout grows up to be. This sort of relationship between black housekeeper and white children was rare. Usually the black "help" were not to speak to anybody white that way. Atticus had clearly seen Calpurnia's qualities as a person and wanted his kids to learn and grow from her.
