"I am sure that the experience of growing up in the heart of the working class and learning from my parents, and especially from my grandmother (who also worked on a barge boat as a cook and a servant for rich folks in Manhattan, Newport, Grosse Point, and Sewickley, all havens of the very rich), that life was not especially fair and always full of bad possibilities, helped shape my future take on life. Then what really transformed my thinking was the war in Vietnam and trying to be a good teacher."
