Where does Calpurnia take the children?
While Atticus is away for work in law, Calpurnia is in charge of the children. When Sunday comes, she wants to take them to church. So, she along with Jem and Scout go to Calpurnia's church. It is a black church, which offers Jem and Scout a new experience.
As soon as they arrive, a woman named Lula opposes them. She does not like the idea of white children in a black church. She, therefore, accosts Calpurnia with strong words. Here is the text:
When Lula came up the pathway toward us Calpurnia said, “Stop right there, nigger.”
Lula stopped, but she said, “You ain’t got no business bringin‘ white chillun here —they got their church, we got our’n. It is our church, ain’t it, Miss Cal?”
This shows that racism comes from all sides. Lula could not stomach white children, no matter how young or who, coming into what she viewed as her "sacred" space. The irony here is that she probably did not know that Atticus would be the one to defend Tom Robinson.
