“When I woke up this morning, I tickled Mousie’s tummy. But Mousie didn’t wake up.” A small boy’s reaction to his pet mouse’s death is handled with great sensitivity by his parents and with great skill by author Robie Harris. “I have something very sad to tell you,” the boy’s father says with his arm around the child. “Mouse is . . . dead.” In this important and comforting story, the child expresses his anger, and then grief, with tears. But he also has other outlets as he prepares a box in which to bury Mousie, putting in some of his pet’s favorite things, and then goes through the ritual of a burial. His confusion and fear about death are also touched upon. “Dead,” says Daddy, “is very different from sleeping.” Harris’s text is an exemplary treatment of a difficult subject for children and adults alike.
