Sleeping In?

Wow, I was supposed to go for a family dinner last night at 7:30pm, and my cousin called me at about 7:30pm wondering where I was. Evidentally I'd slept in! I remember going to bed at about 8 in the morning and being woken up by a couple phone calls which I didn't even answer. So the good news is I finally got a decent day's sleep. The bad news is I better set my alarm clock, even if it's for an 11:15pm shift. Weird.
