This is just an observation. YMMV, of course. But I've noticed this with increasing frequency in recent years...
It's not necessarily a "new" thing. Lying certainly isn't new. But I imagine there must have been a time when, hypothetically, you could make plans with someone, or discuss something, and they would damn well hold to it/keep their word...
Like, in my observation, this happens all the damn time: people flake, people change their mind at the last minute, people ghost (and I do it, too), people, worst of all, change plans, or change their mind, and don't even tell you...
I'm not talking just with women, either. My male "friends" do this. My family does this. Constantly. Randoms I meet, and plan to meet up with later, do this too. And sure, I'm a common factor, but I see this happening more generally, to all manner of people I know, too.
I really, really wish that we "as a society" hadn't normalised this... "Flaky", noncommittal, "my needs come first, always" bullshit...
I really, really do.
If there's a culture where keeping your word and actually committing is still the default, I look forward to one day finding it. Because I am yet to really... Ever experience that. And I've travelled fairly widely and met a lot of people.
I tried to explain that so much to people in 2020 and most never got it. They just couldn't get why I was not okay just being expected to sit around by myself and do nothing with no end in sight. I mean I've never been a social butterfly or anything but I learned really quick that with nothing to work towards personally and no personal interaction, I was basically already dead. Breathing and eating is not living.
