I loved PF's one-liner.
I somewhat agree with Buckmaster. I don't think there's been a total loss of courtesy, but, like the economy, it has taken a serious hit. It's been a while in the making. It seems that such things just aren't taught or practiced as much these days. One can't help but wonder why? The comment about PC could explain it, or at least a chunk of it. Of course, what do you expect when those people are often the same people who don't cover their mouths when they sneeze or cough in public, act as if 'No Smoking,' 'No littering,' or 'No parking' signs don't apply to them, or treat everything and everyone around them as if the rest of the human race and its objects exist solely for their use, or that other people are lesser souls than are they? Does it happen more often in larger cities where one might tend to think that they more easily escape individual notice, or that no one's really watching, or that they blend in with the crowd? The brash ones simply 'dare' anyone to call them on their behavior.
I disagree with Doove's assessment of the 'gentility quotient' of NY vs the south. The day that NY, or maybe just NYC is considered 'generally' more genteel than anywhere south of the Mason-Dixon line will be the beginning of the end. In my work, I've met 'several' folks from metropolitan NY/NYC, and on the whole they believe themselves to be more superior, the only ones in the entire country with a clue. They're generally brash and brassy, and dismiss others with the same concern as a used food wrapper. The few rural NYers I've met do seem to be a different breed however; more like "everyone else." Some rural NYers don't even like the metro NYers. So even from my limited sample, NYers are evidently not entirely homogeneous, and that would be a good thing.
The change didn't have anything to do with whoever was or is the sitting president, though. It's a change in the parents. If your momma wasn't taught manners, chances are that you weren't either. It's related to the same missing parenting that causes the need for 'ethics' classes to be taught in college for Pete's sake..
Very occasionally, when I hold a door for someone and they don't say thank you, I say to them over my shoulder as they're passing through the door "you're welcome," whereupon they walk away even faster, or sometimes look back in mock horror.
Unfortunately, there is also the occasional woman who seemingly believes that to allow a man to hold a door for her is a sign of submission to, or tacit acknowledgment of an imagined subservience clause. They go out of their way to find cause to be insulted. I don't get it. I'll take my lumps on that one. More moments about which to shrug one's shoulders I suppose..
Cheers, y'all... ;-)
