Independence, self-reliance can be vitally important to building self esteem. Say ones parents visit, and before they leave they buy a bunch of dishes as a gift. It's generous of them, yeah, but there are implications. Maybe the person is happy with their dishware situation, or doesn't like the style, but what can they do? Accept the gift, and be reminded of the shame every time they open the cupboard, or refuse and come off as an oversensitive, ungrateful asshole.
Sorta-kinda based on real events except it was just a bunch of cleaning supplies. Consumable gifts are superior in that way, because everyone runs out of consumables.
I love holding doors open for people because it makes me feel good. But I've noticed it's sometimes a bit awkward, particularly when I was a young kid holding it for some healthy adult. I did it to feel generous, but in retrospect I'm pretty sure a lot of those people would have much rather I didn't. Mostly strong guys who probably felt a little emasculated by this little kid, but also women trying to cultivate the same self-reliance. At least I held the doors for everybody regardless of gender (I never really thought to discriminate, every closing door was a chance to feel benevolent).
I play support classes in online games to feel superior to others. Same thing. Though now it's more of a habitual playstyle heh, and I really doubt people mind much... But I'm not actually being generous, just taking the comfortable position of apparent moral superiority.
I guess in short, even if someone gives a gift with no expectations in return, that can be legitimately uncomfortable for the receiver. Particularly if they're trying to build self-esteem through independence. It's not wrong to want to feel benevolent, but it can be unintentionally... patronizing, maybe? Disrespectful, technically.
