People are so quick to jump to conclusions. When I was a kid (say 18-21) I used a ploy to get rednecks to pick fights with me. I'd talk like a guy with a hare lip. You know, "Nyuh-nyu-nyuh", and all nasal. It didn't always work, I'm too big for most guys to want to fight. But a lot of "tough guys" fell for it, assuming anybody who talked like that must be feeble.

Don't always assume that anybody who "talks smart" IS smart.
