Ch.23.5. When Scout begins felling generous and friendly toward Walter unningha , what does Aunt Alexandra say ? How does Scout react to her ?

Upon learning that his father believed Tom to be innocent, Scout wants to invite Walter Cunningham over for lunch more often, but Aunt Alexandra puts her foot down, saying that the Cunninghams aren't the right sort of people for Scout to spend time with. Scout can be gracious to Walter and polite, but can't invite him over because "he is trash."
