“Sam, come push me!” Henry yelled excitedly as he jumped onto the park’s merry-go-round. “Sam! Push me! Sam!”
Sam and Ralph were over on the park swings, thrusting their legs back and forth as they swung to see who could swing the highest. Ralph was in the lead, and he squealed happily every time he hit the peak of his backwards swing, facing straght downwards to the woodchips nearly six feet below. Only centripetal force kept him on the swing, but he was much too young to know about that.
