Farmer donates land for a park
If you are my friend and I gift you a nice item … I would be majorly pissed at you and would not talk to you ever again if you would sell it online.
I would expect you give it back or pass for free to someone who is also close to you.
When you put it that way, i disagree. A gift is a gift. Once you give it to someone its their's to do with as they please. A gift with strings is not a gift.
This story is different though, the farmer sold the land for cheap in exchange for some conditions. This situation is more like going back on a contract.
