sooo... I managed to sleep through my alarm clock.
that had been going off for FOUR HOURS.
I didn't even go to bed all that late.
well, your body just took over and decided things for you. Mine does that sometimes, too! good thing, really, since when one's body is unhappy, the rest of one is, too. pretty impressive being four hours late -- even I've never done that and I'm late all the time! ;)
