You know, I don't get it.
I usually greet everyone I see, whether someone known to me or not.
And I need to point out I was doing this while living in Pennsylvania and New Jersey, too--not just in friendly Nebraskaland.
Surely in my lifetime, by now I've done this tens of thousands of times, and while there
might have been a rebuff or two, I don't recall any.
Inhabitants of New Jersey especially seemed to like it; I made friends left-and-right, hand-over-heels, in New Jersey. To this day, I consider New Jerseyans some of the nicest people one can hope to meet.
As for the easterners who get rebuffed by other blue-staters, maybe it's their approach, their manners.
I can't imagine
not letting a person, even if a stranger, know that I've seen something distinctive in them.
