My Shadow is a poem by Robert Louis Stevenson.

I see him jump before me when I jump into my bed because I have a shadow that goes in and out with me.

The funniest thing about him is that he likes to grow fast, even though he gets very little and he shoots up taller than an India-rubber ball.

He doesn't have a notion of how children should play, and can only make a fool of me.

One morning, before the sun was up, I rose and found the light shining on the flowers, but my shadow, like a sleepy-head, was fast asleep in bed.
