One of our friends has literally become a douche and a dick since he started playing DayZ all the time. He used to be quite considerate and generous, you know the sharing type? Now he's moody, selfish and keeps to himself. When we finally do get him out, we can't even goto Taco Bell without him pushing us out of the way to hoard all the hot sauce, like it's the last fu**ing food source on earth. I joked once that we should pull over at this army surplus store and and stock up for the apocalypse, everyone else laughed, but he just stared coldly out the window plotting and planning his survival.
