Walls made of wood And the roof was the sky Gates lead to mystery But we never asked why. Our back yard was big It was our whole world, And we filled it with the imagination Of a dumb boy and a clever girl. When dad built that sandbox And filled it with sand, We built worlds for our toys And towers so grand. How could a little wooden box Be so amazing and cool? The thing got even better when Mom and dad put in a liner and made it a pool!!! Little worlds for children, Microcosms of play And make-believe Too bad, too bad we can't stay.
