Mrs. Paley received her education both on the East Coast and in the South, creating for her a combination of social beliefs. Mrs. Paley was an eager young teacher who relished the idea of teaching children of different races in order to give to these children the wisdom and equality that she believed she could offer. However, as Mrs. Paley began teaching classes of mixed races she discovered things about herself that left her questioning her own sense of racial equality.
