My Shadow

I have a little shadow that goes in and out with me, And what can be the use of him is more than I can see. He is very, very like me from the heels up to the head; And I see him jump before me, when I jump into my bed. The funniest thing about him is the way he likes to grow— Not at all like proper children, which is always very slow; For he sometimes shoots up taller like an India-rubber ball, And he sometimes gets so little that there’s none of him at all. --Robert Louis Stevenson Shadows What makes a shadow?
