What does Momma say in regards to talking to White people?

Mama is old-fashioned, though, as she teaches the children to behave as she was to behave as a child, and teaches them to act according to outdated racial codes of behavior. Angelou has a problem with this, since she sees that many white people don't deserve her Momma's courtesy, and these rules should be done away with. However, Momma does hold a certain standing in the community; there is a story about how she was called Mrs. in court, by mistake since she is black, but how many saw this as just confirming the respect she has in Stamps.
