Little Duck is watching the sun go down. It is getting lower and lower, but his shadow is getting longer and longer.

Old Tree says, “That's easy, Little Duck. The sun goes down every day, and we grow older everyday. Your shadow grows longer because you are growing taller. You are becoming a big beautiful bird!”
