Rex is a very little boy who says he's a dog. He knocks on a strange man's door and announces he's moving in. The old man plays along, letting Rex Fetch the newspaper and patting his head, then insists he go home. The man resembles Einstein, the boy a skinny owl--it's all in gentle orange, gold, and olive watercolors, diffused with light. A tender story full of offhand, understated humor, more suited to fond mothers than to their offspring, who may well find it pointless.
