“[Mayella] was as sad, I thought, as what Jem called a mixed child: white people wouldn’t have any to do with her because she lived among pigs; Negroes wouldn’t have anything to do with her because she was white.” pg 256 chapter 18
This quote shows poverty and discrimination. Mayella lived in poverty “among” pigs so the white people would not be nice to her or hang around her because of that. She was isolated from the white community because of how she lived
Mayella was white, so the black people would not have anything to do with her. Even though she was isolated from the white community because she was poor the black community would not accept her because she was white. Mayella lived an isolated live, by herself.

“You ain’t got no business bringin’ white chillun here- they got their church, we got our’n.” pg 158, Chapter 12

This quote shows discrimination . Lula does not want Jem and Scout in the First Purchase African M.E. Church. because they are white, this is Lula discriminating against Jem and Scout. It shows Jem and Scout how being discriminated against because of something they can’t control feels. This is probably the first time Jem and Scout have felt discriminated against because they are white. Lula does not think Jem and Scout should be at the First Purchase African M.E. Church, because they are white and they have their own church. I think this experience teaches Jem and Scout to not discriminate against other people. This whole chapter shows Jem and Scout what life is like on the other side of the tracks, giving them the experience of seeing how their fellow humans live. This shows them why Atticus does not discriminate and shows them why they should be kinder and nicer to their black peers.
