I suppose everyone thinks they are courteous—in their own minds of course, but are they really?
It only takes a second or two to hold open a door, say please or thank you, but it is rarely heard out in public now. We are more likely to hear a couple of people arguing, saying F you or worse and out loud voicing their personal opinions about others’ clothes, manner, orientation, race, etc with not a shred of remorse.
If you watched the news about the Academy Awards and saw Will Smith slap Chris Rock, even though he might have deserved it, it was not surprising. I like both celebrities but Chris Rock made a rude joke and should have been admonished, but behind the scenes. I used to watch comedians a lot but now they are so blatantly rude I don’t care to hear them.
In general, my opinion (and you know I always have one🙄) is that general courtesy went missing even before the pandemic. Anything and I mean anything goes these days.
