@Joe Nation,
I'm related to a few of the 'never-wrongs'. All I do, as they twist in the wind trying to prove it, is tell them, over and over again, that being wrong does not make them a bad person. My stepson in particular seems to feel that being wrong about something, whether it's a silly trivia question or the state capital of Oregon, is a personality flaw of some kind. The constant pressure these people put on themselves is sometimes very sad. When they're proven wrong you can see their devastation. My aunt actually gets pissed, like you've insulted her. Crazy.
