(D for Douchebag)
I'm visiting New York City right now, which is where I'm from. I noticed while traveling around on the subways and walking down the streets that people in New York City can be quite gruff and rude at times, especially with regard to exhibiting a general lack of patience. (For example, rather than saying: "May I please get by? Thank you." when someone is in their way, a New York City resident might be more inclined to say: "Move your ass!", or: "Get out of my way!") I seem to remember this from previous experiences. In fact, people can be so rude and impatient here in general, which is one thing I didn't really enjoy so much about life in the big city. Oh, but people are getting to be like this everywhere else too it seems, and maybe they always were (and maybe I'm like that too and I just don't realize it).
But it strikes me that eventually the kind, considerate, patient people of the world may revolt and decide not to take such rude douche-baggery any longer, sparking the long overdue "World War D". (Naturally, the new Brad Pitt movie World War Z made me think of this. But you know, zombies can't help the way they act; but people can {but very often don't}. And while protecting oneself and society from zombies may seem like a war, it's really not, because a war suggests an intentional conflict to correct some political difference viewed as worth dying for. But zombies don't have a political difference with the rest of us; they're just hungry, and apparently we're delicious, and neither group can help these intrinsic qualities. But rude, jerky douchebags can actually behave in a polite, civilized manner; they simply choose not to do so; and as such, I can see this as something which could indeed someday spark a war. After all, it sparks numerous fistfights all over the place constantly.)
So in this story (and the movie thereof), World War D, polite people will eventually snap and decide not to take the loutish rude behavior of selfish jerks anymore. Oh, but rude jerks are generally tough enough to push people around, and so they start to win early skirmishes and battles. Oh, but as the two sides begin to form worldwide, the rude douchebags begin grating on one another, and they begin to fight amongst themselves, thinning their ranks and damaging morale. So then the rude douchebag army must initiate a form a discipline within their chain of command and general conduct whereby they are all polite to each other and agree to help one another, etc. Well, with this turn of events, the polite and kind forces call for an armistice and an end to all hostilities, and with the end of the war, the rude douchebags simply forget the way they used to behave and are just nice and agreeable all the time from then on, leaving a far better world behind in the wake of the war. The End.
(Okay, so maybe that's not so realistic, but a guy can dream, can't he?)
