Funny story (vaguely related)...
When I got married last year, some of my extended family flew in from Europe. Their first trip to Arkansas. I was already kinda worried about what they would think, and wanted to make sure they had a nice experience. On our way home from the (very) rural airport, we got behind a pickup truck... Hand-painted rough cammo-looking colors, two men in neon orange jumpsuits (hunters or jail-escapees, don't know), "Don't like my driving, call 1-800-EAT-LEAD" bumper sticker, tail gate open, deer in the back, shotguns sticking out of the cab, swerving around the road like you would not believe... Ha ha ha.
You never know when you'll REALLY make an impression on someone. On the other hand, who cares? People will believe what they want to believe about a group of people, and they will find things to support those ideas, no matter what you do.
I do, however, try to dress nicely all the time, because "look good, feel good, do good" was drilled into my head too long ago!
...That which does not kill me will be the basis for my revenge...
