Some people are born irritants. There is no escaping them. You try to avoid them but they manage to sneak up behind you and ruin your day the best way they can, with the best tools at hand. You are sometimes left wondering (almost admiring) how they manage to do it so well. And when you find that some of them hang out with each other, you wonder... do they irritate each other so much so that the friction sticks them together? Or is the togetherness a method of sharpening their tools against each other, in anticipation of their next victim?
