sleep?

A friend once told me that he thought introverts probably got a lot more sleep than extroverts because after we hang out with people we're energized and have to wind down. (sorry for the run-on sentences, i've been speaking a lot of spanish and am tired. and in spanish run-on sentences are actually proper grammer.) Tonight that is definitely true for me. It's 0:42 (or 12:42 in the morning), I have a flight that I need to leave for at 7:00 am, so 6 hours, not to mention getting up and awake (and the film that I have to return in the morning, since we had film night tonight and we had to rent the film this week). I am fairly wide awake, but writing this realizing that tired or not I had best get some sleep right after I make a list of what I need to make sure to grab before I run out the door in the morning. Uf!
