Dog's intensity, enthusiasm and affection really comes through in this near-wordless picture book. His little playmate throws the ball in the morning, but then she has to go to school. He desperately wants to have someone throw the ball for him, but who will throw the ball? Who, who, WHO? He misses the game he plays with his friend, and he misses his friend. He searches for another way to play ball, finally wearing himself out and dreams of playing ball until...until...until she gets home from school and can play ball again!
