I am Keith. Everything around me is the world. It's not just below my feet. I'm talking the whole of existence here. That's the world. It's a lot bigger than me. It's a lot bigger than you and everybody else.
That's why it's around me and not the other way around. So...I'll show you the world around me, how I see it.
