When I was a kid, we were all taught table manners because a family eating together at a table was considered NORMAL.
Further, social etiquette was held up to be preferred behavior by enlightened folks.
Manners could be a burden if carried too far; it kept things orderly and a sense of decorum prevailed. Mostly.
Films were shown in elementary school and Jr.High about standing when an older person walked into a room, or pulling out a chair or helping
open a door. Courtesy was recommended because respect for others made you a different kind of person.
There were and are many, many reasons mothers and fathers abruptly abandoned teaching courtesy, respect and manners.
Etiquette is gone forever!
"Keepin' it real," usually means something rather socially unplesant is going on--but--it's okay because "real" people do it.
Now I confess, I'm an old guy and I grew up in a different world.
I was taught to say, "Yes, Sir and No Ma'am" to people. In fact, I still do.
My kids do too and you would not believe the praise the receive from strangers for it. It is all too rare.
A counterfeit social order has decended and enveloped the young and the young who give birth to and rear the even younger: social chaos.
It took society in general thousands of years to find workable rules of conduct. Some went way too far, admitedly. But, manners and etiquette
provided us with a kind of aesthetic ritual of social beauty with polished conversation elegant mannerisms even while eating. These do not, for the most part, exist today. Sadly.
The only thing any of us can do is set an example.
Let me tell you something about what I mean. . .
I always thought the European style of using a knife and fork looked admirably polished and sophisticated. So, at age 40 I got a book from the library and studied how to do it! Now, if I'm at a restaurant eating, I've had strangers remark to me how "nice" it looks. Isn't that funny?
When my kids were teenagers and all of us were going to a local Country Club for somebody's party, I rented a video about etiquette (i.e.napkins, proper forks, knives, whichs spoon to use, etc.) I sat with them and watched it.
Afterward they looked at each other and at me and nodded.
At the party, it was a lovely thing to behold! I see them eating out with their friends and those companions are invariably mocking in tone--AT FIRST--yet, eventually they admit it really looks wonderful.
