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.
As someone that hates breaking their own word this exact problem keeps me from a lot of social interactions.
As my health is quite frankly abysmal (nothing serious just highly inconvenient) I am very much hesitant to promise to do things yet it seems like more and more people just want that promise even of you don't keep it.
Oh well I'll stick to my principals either way, to the best of my ability at least.
