Very badly.
It was forced upon me without ever explaining to me, growing up.
Now saying "thank you" felt very unnatural and cringy that no amount of gratitude practice felt good.
Like how I eventually learnt humbleness, I don't think I'll learn what gratitude and appreciation ever actually means by having "not enough" (or by living with scarcity in case of my upbringing).
I think I can only ever learn such concepts by sheer contrasts of experiences and nuance, not being stuck at one place (whether lack or excess) then "BOOM!"
realize 'this is all I ever get, I should be grateful'.
So far, no amount of grace and luck made me thankful. No amount of kindness did, no amount of leniency did.
Probably because it was unasked for. Unanswered, unexplained. Thus I still consider myself as one of those ungrateful types.
If I ever learn gratitude, it probably meant I already got most of everything I wanted in life.
It's likely that I'd be able to be appreciative if I were more independent and be reliably living my own life, than being more or less dependent (or having to be forced into interdependence) on the kindness of others and fate itself even.
