The wannabe nerds, like me, end up partially adapted to human society, neither fish nor fowl. But real nerds piss people off right and left with nary a clue. Some people disagree, and say that what I'm describing are simply boors. It's true, neither boors nor nerds grok people. But there's a difference.
Boors are anti people-skills.
They corral you at the party and won't let go, and nothing will dissuade them. Their ultimate evolution is the Jehovah's Witness. On the other hand, nerds are merely uninterested in people skills. They'll sit quietly until the conversation turns to something interesting, like how much RAM is optimal for a Web server, will loudly derive the solution by constructing a simulator out of olives and celery sticks, and will shut down again. If you were to give a nerd the algorithm for people interaction, he'd use it when appropriate if he didn't have anything better to do.
