After going to church with Calpurnia, Jem and Scout learn a lot about her that they never knew. The children realize Calpurnia is an accomplished individual with many unique abilities that they were previously unaware of. Jem and Scout soon find out that Calpurnia has a life of her own, and is able to communicate effectively with both white and black people. Scout notices how Calpunia talks differently at church when she is around black people than she does in the Finch home. Calpurnia’s ability to code-switch, depending on the setting, is a unique ability that intrigues the children. Jem and Scout learn that Calpurnia is older than Atticus and that she grew up near Finch’s Landing. Jem and Scout realize that Calpurnia is one of the few literate African Americans in Maycomb. Jem learns that Calpurnia taught her son Zeebo to read using only the Bible and Blackstone’s Commentaries, which is very impressive. The children are in awe after finding out Calpurnia’s life story and want to spend more time with her.
