You know you want something, and you know it'd be bad for you, and you know you shouldn't want it, and the more you think about how you shouldn't want it, the more you do?

It's like that.

How the more you think about it, the more you become obsessed by it, and the more you have to have it, and the more you think about it?

Exactly like that.

And when you close your eyes you see it, breathe in, you can still smell it, and you think you could just touch it if you only tried hard enough?

And if you did, you'd burn yourself.

But in those few moments, there'd be bliss.
