What's amusing is that I've tried to do this nowadays, where I make plans with someone a few weeks in advance and then just show up. Only to have them not be there, and when I ask what happened, they said, "oh, I didn't think we were still doing that, you hadn't said anything about it in a while"
The protocol we have always implicitly used in this case is 'no news is good news'. I.e., participants in the meetup understand that they only have to communicate 'I won't/can't be there.' The reason is optional. Could be lots of things.
But socially this has gotten inverted.
I have several very long relationships with people (>30 years) who are overwhelmed by this. Living their lives immersed in constantly buzzing irrelevant social noise.
It’s kind of funny that business etiquette has moved much more to scheduled meetings even for short discussions, and social life has moved in the opposite direction.
At higher levels, I think impromptu calls/messages of a time-sensitive nature are probably more common. But, in general, phone calls out of the blue are less accepted than they were 10-20 years ago outside of a very close circle. And in business there would probably be a preceding message to the effect of “can we chat?”
Yes this is one of the few things that have actually improved over the last decade or so. I love this practice of asking first.
It depends. My friends with kids have everything planned out months in advance. If they're to come out to something they have to have it all scheduled between judo classes and school birthday parties blah blah
The rest of us just wing it. Which I really prefer. I hate having plans. Especially in case I might not feel like it on the night in question.
