Today I am what you call a cage.

"He" cant see me, but I'm all around him. 

While he sits in his chair for hours, all i do is wait.

For what?

I don't know yet.(remember this)

Time and time again he escapes my bars. Runs away, and comes back.

Why does he do this? Does he miss the isolation that only I offer him?
Maybe so.

I don't know him, even after all these years. he never speaks and his mind is a secret. 

But what i do know is that he hurt me, i had nothing to do with it yet he hurt me. 

Life is strange and so is he.
