Read the excerpt from Richard Wright’s Black Boy. My mother finally went to work as a cook and left me and my brother alone in the flat each day with a loaf of bread and a pot of tea. When she returned at evening she would be tired and sometimes dispirited and would cry a lot. Sometimes, when she was in despair, she would call us to her and talk to us for hours, telling us that we now had no father, that our lives would be different from those of other children, that we must learn as soon as possible to take care of ourselves, to dress ourselves, to prepare our own food; that we must take upon ourselves the responsibility of the flat while she worked. Why does Wright include this text?
