Best of luck. I also overslept this morning. The fiancee got up with the alarm, got ready and left without waking me. She usually at least stops by to say 'goodbye' (and 'you should really get up now') but either she didn't or I was oblivious to it. I was having one of those "back in school taking a test that I hadn't prepared for" dreams. I spend most of the dream wasting test time getting set up, moving my desk about, discovering that the booklet that I intended to write my answer in was already filled with notes from another class, etc.
The way I figure it, if your body refuses to wake up to a loud alarm, then you need the sleep. Nuts to anyone who says different. But it really is the case that after Army NCOs a lot less stuff intimidates/alarms you.
Speaking of which I 'met' our new physical training instructor. The man could have been any age over 30. He looked like he'd been made from equal parts chewing tobacco, rawhide, and bastard. Fething terrifying.
