This book was made because his son was afraid of the dark at three years old. Most of the time, he would just show him the pictures, and he would laugh about Buttons running away from noises in the dark. Then by the time he had shown him the whole book, he was asleep. Most of his books are that way because of a need that needed to be filled-usually just to see the smile on their faces. That's all he ever needed-smiles and laughter.
