It's difficult for most children to imagine their parents ever having had a childhood, especially an energetic one doing the very things that the children enjoy. So it is for a little boy named Peter, whose father never seems to be satisfied with Peter and hardly ever smiles. One day Peter shows up on his grandfather's doorstep, seeking asylum after breaking some "stupid ole purple thing" on his father's dresser. Grandfather takes Peter in, and the two have a long talk. Peter learns the significance of the purple thing and much more about a father who as a young boy loved running more than anything and told silly knock-knock jokes. Peter gains a beginning awareness of who his father is and what their relationship could be. Johnson's art is stiff and posed in some spots, but her heartfelt story of African American males and their blossoming kinship deserves a listen.
