Who does Junior play with? Why is he forbidden to play with the others?

Geraldine has explained to her son that there is a difference between colored people and niggers, and that their family belongs to the first category. Colored people have standards of behavior more in line with white bourgeois sensabilities, or, as Geraldine would put it, colored people are clean and quiet and niggers are dirty and loud. She has always encouraged her son to play with white children.
