When Lula came up the pathway toward Calpurnia, she said, "Stop right there N*****."
The kids just realized that she said that word in front of them and they never heard her said these kinds of words when she was at work.
The kids felt left out in the church so they said, "Lets go home Cal they don't want us here."
When they got inside they talked about how she was talking and she was talking with those words coming out of her mouth.
"You're not gonna change any of them by talking right they've got to want to learn themselves, and when they don't want to learn there's nothing you can do but keep your mouth shut or talk their language." Then Scout and Jem just went up stairs in their bedroom.
