We went to family for Xmas day/eve.
We took: two bottles of spirits, one a premium whisky and one a standard gin.
All the food for Xmas eve meal that I cooked.
Mixers.
An anonymous card with cash in (because they wouldn't let us contribute to the food for Xmas day, they were hosting loads of us on two occasions and it didn't feel okay they had all that expense).
We took home our opened whisky and unopened gin. And the mixers that we didn't drink.
Don't feel remotely grabby tbh. Or CF.
It's about context - we often host those particular family members, they don't drink whisky, it wasn't amazing gin. So definitely not a gift - I only gift nicer alcohol, and I took it to be drunk by me instead of me drinking theirs. As it was, I ended up not drinking other than one glass of wine with dinner. And the beer I took as well.
I think saying it's CF or grabby, is too broad stroke without considering other factors.
If another family member did it, yes I would feel it was CF/grabby, because they didn't and don't ever contribute. But we do, all the time. So it evens up, and I'd entirely expect them to do take theirs back.
