Kiss me through the wall,
Yet, don't touch,
Stay away and awake,
Be my one and only when all have left,
Be what you are meant to be,
Be my shadow.

It doesn't make sense. But essentially, a shadow is something that you want to touch, but can't. It is the only friend you have, when others have gone. You cannot tell if it is awake or asleep. But all this it must and does do. That's the law of nature. That was its only purpose of creation. To be an obscure friend to man.

I have this theory. Shadows are leeches. Souls that have no body of their own. They attach themselves to living bodies, in hopes that they may be able to inhabit it someday.

Scary thought. But definitely an interesting way to look at things.
