" You never really know. Lately Kevin has been bothering himself with the idea that nothing is certain, nothing can be proven. Not one thing, not in all the world. The sun will rise tomorrow. Prove it. The sun rose this morning. Prove it. The sun is in the sky. Prove it. There's a sun at all. Prove it. The world is like a box of Kleenex, every doubt pulling another along behind it. You can always find a new reason to distrust the facts. "
