Everyone knows that it's going to end on december 21st 2012, not tomorrow... </plug> If it were to end tomorrow rolleyes I wouldn't bother getting off my ass to do anything...since everyone is going to be dead tomorrow anyway. I'd probably be here sipping tea and reminiscing about everything with the lights off & play some of my favorite video games... Or have a great meal, get drunk and get laid. Undecided as of yet. It's actually quite a realistic possibility that everyone realizes that the world would "end" (or atleast the human race become extinct) in a day or other similar short period of time... think asteroid crash. We would all be sitting here waiting to die.
I would tell everyone that I have ever known that I love them. I would try to get my family together and be with them. Then, I would hope the ending could be reversed by mice. Hitch Hikers guide to the Galaxy.
