Am definitely feeling drain-bamaged this morning. Getting less than three hours of sleep will do that - didn't get home after the quartet gig until 4, and the alarm went off a few minutes before 7. It's a good thing the guy I'm subbing for today starts off with a pretty easy class (web page design)...only 5 kids (3 of whom are here), and they're working on a resume project. It wouldn't be very difficult to fall asleep. :-P Math classes the rest of the day won't be nearly as easy - will have to be at least slightly awake for those...
