As a kid my mum went into the school to tell me teachers to stop letting me share food with others because other kids took advantage and I was na?ve.
Nowadays, mostly no unless it's my parents or my best friend (who is like a sister to me, known her for 20+ years). I'm more the type of person that if we go to a shop or out for lunch I'll offer to pay for your share rather than just hand over some of my own food!
I'm possessive over a lot of things, but food is not one of them. I love sharing food, and I guess that is because I'm so used to doing so with all my (many) siblings.
Greediness isn't ever allowed in our household ovo it's kinda like a set rule, so even if I wanted to hog my food, I would be in serious trouble...
It really depends.. I usually hate sharing my food, though. And if I do share, it's because I love that person very much. I refuse to share soup though, it's my favorite food lol. But I'll share like chips and dip or dumplings and stuff like that c: Or even bites of my pasta/steak. I'm skeptical about sharing potatoes, though.. I really love potatoes as well..
