There's a chair in the corner of the room. It's not there when you look at it. Not directly. Only when you're not. Just... out of the corner of your eye. You can see it if you look. Without turning your head. Just let your eyes wander. See it now? Doesn't it look familiar? I think so. It does, right? You remember now. Where it's from. Why you can't see it when you look at it. It's not there when you want it to be. Only... when you don't. When you want to stand up, to leave. It's only there when IT wants to be.

Sit down.
