I had a wonderful moment this morning. My alarm went off and I was out of bed before I'd really even woken up. I looked at the clock and I thought, "Wait a minute... Why did I set the alarm? I don't have to get up. It's Saturday." I got that great, great feeling that comes with the knowledge you get to go back to sleep.
Then I realized that I was mistaken, that it was Tuesday and that I really did have to get up. Which is a really, really shitty feeling.
