Seeing as you don't even have the consideration to post your home state, how can we but wonder where the hell you're coming from and for whom you speak.
I'm from NYC, but I travel extensively into the burbs, midwest, and pacific northwest. Further -- I talk to everyone I meet. I talk to the lady waiting tables at the Waffle House, the guy tending bar at the airport theme bar, six businessmen out for a night on the town in Vegas. I'm the guy on the airplane in coach who talks for six hours to the grandmother traveling cross country to help with the new baby. And, too, I have friends scattered across the country.
Likewise, I have seen the kinds of kids going to NYC's specialty high schools as well as places like Dalton and Martingale, etc.
And I promise you, what I am saying is not meant as an insult, but simply an observation that has caused me some distress.
