your english is actually really good. better then most people I know.
Anyway, I'd learn EVERY language spoken fluently. Then I'd go find my soul mate and turn her, because immortality is crap when you have to spend it alone. Maybe turn a few friends too, but close friends, other wise i would get tired of seeing them. Then I'll putz around about, talking to the greats (depending on when, like if i was born at the start of time or something, people who are dead but were great, but if today, then great people today.)
I'd learn to master the broadsword, and the rapier, EVERY popular dance (doesnt matter the culture) and learn to play an instrument.
Finally, if i found some time, I'd go to that Robert Patterson kid's house and show him what a real vampyre looks like. X3 Sorry, couldnt resist, and you will probably see a lot of twilight comments. Besides, I think i'd be doing the world a favor.
