You are right--there is nothing wrong with having less so that other people can have more.
Nothing at all.
But it's not really "sharing"--it's "giving away" or "giving up."
And we should be accurate about it.
Wait, if that's the case than what constitutes "sharing"? Wiki says that sharing is "the joint use of a resource or space," but it also says it is "the process of dividing and distributing." They also point out that sharing "disjoints the connection between usage and ownership of a product." I think the confusion comes from issues of ownership, the idea of borrowing instead of technically sharing, and what item or resource is actually being dealt with. You don't share an item like a dump truck or toy the same way you share food because food is a finite, single use resource.
To bring it back to the thread topic, the problem comes from the mom offering to divide the cheese sticks that the daughter felt belonged to her. Obviously since the daughter couldn't expect to get the cheese sticks back

, her mother was effectively giving them away. The only problem is that not everyone feels they were hers to give. I personally don't feel they were. She could have asked her daughter if she wanted to share her appetizer with the others. I think most people say "share" when they really mean "give away," but that's semantics. I choose to say share instead of give because that designates resource distribution from gifting: I would not say to someone "Here is the birthday present I am
sharing with you." Sharing may mean something belongs to nobody unless it belongs to everyone, or it may mean something belongs to somebody who is going to distribute it among everyone. It can also cover borrowing and lending and that's a whole 'nother ball of wax!

Sharing as a word suggests generosity. Imagine if someone asked "are you going to give that to me?" instead of "are you going to share that with me?". Which sounds more polite? If they asked the first way, you might think they wanted the whole thing, not just a share.
Dividing resources suggests that whoever is responsible also retains their amount - if you share things you usually keep some for yourself; if you give things out or away then the amount you keep can vary from your equal share, to less, to none.
I guess giving and sharing are not the same thing, but they are definitely interrelated and both are considered polite and generous.
As long as you are giving or sharing things that belong to you.
