I was supposed to call someone tonight at 12:15am. At 11:45 pm I was already getting tired but went up to my room to get settled in and call in a few minutes. The next thing I know I'm waking up and it's 3:30am.
I also did this earlier today. I was supposed to call at 11:15am. I got up at 8am and got started with some programming within a couple of hours. The next time I look at the clock it's 12:30 pm and I mutter "Oh frick".
I think the last late-night call I managed to make without falling asleep, but then promptly excused myself to go to bed.
This should probably teach me not to make late-night commitments when I can't seem to stay up late enough to keep them. I'm going to have to apologize again now. I really didn't mean to miss it.
