You wanta have fun? Get on an elevator in any large northeast city. Once the doors close, try to make eye contact with the folks ridding with you. They’ll cringe in a corner before they’ll look you in the eye. Strange lot, they are.
I used to have to travel up North on Business and it was a real eye opener. They looked at me like I was from Pluto for smiling and saying How are y’all doing today? I guess its just not done. Fortunately I have not been above the Mason Dixon line in about 20 years. :-)
