Yea my partner grew up genuinely poor and it’s interesting seeing how it impacts their mentality. The simplest but clear example is they never finish low-perishable food they like until they have more of it. There is always a few potato chips left in the bag. One cookie left waiting till it’s necessary to get through a rough day or more are purchased. They are the best saver I’ve ever met. But it wasn’t until they got lucky and got a break that it mattered because they never had anything to save but cookies.
A close friend grew up in first-world poverty (meaning, warm house, state-supported education, health care) but experienced no luxuries. To this day, they will buy themselves a tub of ice-cream or chocolate and eat it all completely alone, almost hoarding it, because growing up they had to share everything with the many siblings. It's crazy how weird pathologies we humans have.
Money psychology is interesting in that people often end up being traumatized by their parents into behaving identically when the circumstances no longer warrant it, OR have a knee-jerk reaction living their life completely the opposite way because growing up that way drove them insane.
A similar thing happens with children of parents who came out of war zones or famines. Sometimes the children are explicitly taught that violence or starvation can come at any moment. Often they learn to feel under threat implicitly by picking up their parents’ affect, without any message or lesson being clearly stated.
I find myself doing that. I'm not sure if it's just a silly habit I have because I don't like to run out of anything even if it is not important or if I picked it up from my dad who lived through the "great" depression as a child.
Conversely, I had an acquaintance that grew poor, and would finish 95% of the cookies in a bag, but always leave the almost empty bag to the next person to find out, even if it had to stay that way for months.
The 'blank in the firing squad' technique of snacking is a pretty typical girl thing.
Eating cookies? Perfectly fine. Eating an entire bag of cookies? Gross. Unthinkable.
But how many cookies is really fine to eat? The safest best is not to know, either by breaking them into uncountable pieces or leaving some in the bag for someone else to finish (meaning, you ate less than a bag of cookies and are safe).
I do this, but it's not really about if it's "gross" to eat a whole bag or not. I don't feel like doing that anyway. It's mostly that if you share food, I think it's considerate to leave one if there's more than one left. Someone else might be having a really bad day, but a small consolation could be that they didn't get home to discover there aren't any cookies left.
I do it to avoid being blamed, I don't know what you're on about. I've never cared that much about the semantics of how many cookies I ate (then again, I'm on hacker news so I might not be the best representation of the female populace)
