Time. It's a weird thing. As a human, I don't find it consistent. If everyone wasn't talking about it, I would doubt its existence. Perhaps I am anyway, but time is not an easy thing to disregard, whether it really exists or not, given that so much in the human society are ruled by it.

Also, I've eaten a lot of cake lately. I will be eating some more later today. That, at least, I do not doubt.
