Sick is a relative term.
Monday, not yesterday, the day after I got back from the reunion, I called in sick. I really was well enough to go in to work, but I was quite exhausted from the weekend. I also thought about going in late even though I'd called in sick. Then I got a really bad headache & layed down in the dark & ended up falling asleep.

When I'd gone into work the next day, the guys busted on me that I took a sick day so I could sleep in. So, it's pretty much true, but the drive did suck a lot of energy out of me. I didn't even get anything productive done around my room at all like I'd originally hoped. Ah well, c'est la vie.
