It was a cool summer day. The wind blew briskly, kicking up dust here and there, pushing the swings to and fro, flipping Bobby's hair this way and that. Bobby sat alone in the park. She was building a house in the sand. The house was fine she thought. Yet something seemed to be missing. I know, Bobby determined, "A tree! I need a tree for the back yard." So off she went with her plastic shovel and water pail into a thicket nearby. Bobby was the best little tree finder, for she could crawl into spaces and under branches where no adult would go (only animals and little children were allowed.)
