pray that whatever wiped out the entirety of the human race kills me quickly and painlessly so that a can join my family in heaven. that is most likely what i would do...
I would probably go to the library of congress, and set up a new home there. I would then raid a gun store, and start living my life similar to the way jack did in lord of the flies. I would keep doing this until I was no longer able to continue this, and then blow my brains out to save myself the pain of dying slowly.
I would proberly go and Spend heaps of time researching how the Human Race was almost Terminated then once I figure out how, I will Study how create Atrificial Humans and Robots and make a whole new City and then a World, I will be the the richest man in the world with everything, Then 1 1-2 years later I will be killed cause the robots turned Evil and the artificial Humans Where dying so quickly from Disease and other weird contagious stuff.
So began the WAR Between Artificial Human and Robots, Not long after the Humans were wiped from exsistence, and then Robots ruled the Earth!! Lol I guess I should've watched Termanator huh!!!!!!!!
I noticed you said "Last male/woman' So that means I have to repopulate the world by marrying tons of women. Heck Girls will be all over me. As long as they are not bimbos I'll be fine. *Shivers* Bimbos scare me.
