@pony Easy. Is it your life, or your friend's one?
Also, it's useful to think about your legal contract with the world in this aspect this way: _if you get a gift from a party, by that act of generosity the said party voluntarily gives up any and all rights, titles and interests in the said gift and grants you an irrevocable ownership, as well as irrevocable worldwide license to use, modify, destroy, repair or otherwise change, as well as further re-distribute, or not the said gift item._
In plain language: **it's now yours, do whatever you need to do and don't look back.**
