In other words, you're NOT the ONLY Truman . If you live in a large metropolis, then most likely you are in the company of some hundreds of others like you. The survivors are spreaded and alone at the same time. THEY perform over survivors' brains. Thousands and thousands are still to come.

I'm not saying you cannot wish to 'change the world'. Just saying there is no 'world' to be changed anymore , now that the hurricane is over in your city. I suggest you stay alert. At least, that's what THEY want you to believe. That's a LIE, too.
