A little boy sits under a tree and a leaf falls on his head. When the leaf stays on his head he decides that he will be a tree. All day he is a tree, even though his friends warn him that he may be chopped down or nested in, and he remembers not to run and greet Daddy because trees stand still. Eventually, at bed time, (for supper he carefully breathes air and sunshine) the leaf blows off and the little boy then decides to run inside and be a little boy. This is a very natural little story, in which the author has delightfully captured a child's whimsy. The large crayon illustrations, drawn in bright fall colors, are pleasingly childlike. Adults will enjoy reading this one aloud.
