I wonder why the grass is green, And why the wind is never seen. Who taught the birds to build a nest, And told the trees to take a rest? And when the moon is not quite round, Where can the missing bit be found? Who lights the stars when they blow out, And makes the lighting flash about? Who paints the rainbow in the sky, And hangs the fluffy clouds so high? Why is it now, do you suppose, That Dad won't tell me if he knows?
