Alone in the world

Imagine waking up on a lazy Saturday morning and notice you're home alone. Puzzled, you stretch out and decide to sleep for a few more hours. After a solid snooze, you get out of bed and go downstairs. Nobody is home... strange. Assuming everything is fine, you turn on the TV as you eat your breakfast (or by this time, probably an early lunch). You call your best friend to see if he wants to do something today. No answer... strange. Whatever, you can just call someone else. No answer, no answer, no answer. Wow, this is really weird. Ok, I might as well call my mom and see where she is. No answer. Ok, this shit is just scary!! 

You run outside, ignoring the subzero temperatures and notice a particularly eerie silence. Where is everyone?  Now the rest of this could turn into a very odd and rather depressing short story, but the other day when I was in the library, I overheard a conversation between an obnoxiously loud man and an annoying girl. I tried blocking out everything they were saying, but this prompt stuck with me, "what would you do if you woke up one morning and were alone in the ENTIRE world?" Gives me the chills just to think about...
