The little man is very lonely. No one answers when he says hello. One day he makes a poster, seeking a friend. Then he sits down on the step to wait. When a big happy dog with his tail in a beautiful curve sits beside him, the little man makes a friend at last. They play and walk and laugh every day. But then the girl in the polka dot dress comes to the step. The little man watches as the dog put his soft muzzle into the girl's hand and worries that he has lost his only friend.
