Who Am I?

I am everything you hate, nothing you are, anything you want, and something you thought about last night. I am your best nightmare and your worst dream.

I am a clever line of poetry. I am a perfectly-written paragraph. I am a happy melody in a sad song. I am a bad joke. I am a laugh that stays in your throat.

I am action and I am stagnation. I am intelligence and I am ignorance. I am the world and I am nothing. I am understatement and I am contradiction. No, I'm not. Yes, I am.
