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.
That world, or that dynamic, really no longer exists, in much of “mainstream” Western society, unfortunately…
Notably, it does in tightly knit immigrant communities, and it really, really does in Muslim/Middle Eastern ones…
Not so much in our “post-racial” multiculti “melting pot” Western societies, though… Unfortunately…
