Nah, it's just shitty memory. I have had quite the happy childhood, actually.
I don't find myself reminiscing a lot and in the rare cases I do, there are quite some gaps. Even in more recent times. If I really try to dig, maybe it comes back, but I assume it's "use it or lose it".
So, what's your point? Other people might have a lot more boring childhood anecdotes to tell, but it's not like I'm suffering in any kind. I still remember people or useful skill - the stuff I do use.
As an added benefit of growing up quite poor, I probably just had less unique experiences I actually could recall. Like, I've been on three travel vacations overall. Kinda like those COVID years blurred together for most people.
