Yeah, I remember the first day of the Danish equivalent of High School. I was a nervous wreck, but luckily the three years there went on to become three of the best in my entire life.
Anyway, I had no idea they would become that at the time, so I was about to piss my pants (not literally, though :P). Luck would, of course, have it that I broke my toe the day before and I had to wear an enormous cast and walk on crutches.. Ah yes, those where the days :rolleyes2
You'll probably be fine, though.
