If the world really was coming to an end, I would probably contact my friends that I fell out of touch with, spend time with my family, and spend all my money (if it was still being accepted) to splurge for once and for the last time in my life.
I'd go to a freaking New found glory concert. -_-
hey, even if the end of the world happened when I was at the concert, I would die happy knowing at least that was the last thing I saw before I died.
Hm. Well, I would make sure that I didn't die a virgin, I would tell off all the people that I don't like, say what's on my mind, and then I'd eat my neighbor's dog for good measure.
