So my daughter has a friend who is very greedy and likes to beg afterwards for something to be given to her. Actually that's nothing to do with me since she is already over 18 but she really messed up. She gave her an expensive Nintendo 3ds game and told her to shut up and ask (my daughter's words) from now on. But that made it worse and her friend is asking for more and is behind our money. E.g. When she was invited to her birthday and when my daughter gave her 10 euro as a present, she was totally disappointed and even said that she expected more money because her mother (I) often gave her expensive Nintendo 3ds games. When I heard that I burst my collar and I told my daughter that this is not a real girlfriend. She finally noticed it too. Now finally to the question… Do we have the chance to get back the expensive game my daughter gave her? The girlfriend doesn't want to tell it anymore and even gets cheeky. We have the packaging as evidence. Would an advertisement bring anything? I told the story above to show how greedy the girlfriend (now ex girlfriend) is and that she will not hand it out voluntarily.
PS: My daughter has a disability and therefore you have to help her a little with some things.
No, a gift is a gift and repeat is stolen.
I'm sorry for the experience, but you can only undo gifts if your daughter is incapacitated and be glad that she is only disabled, but not incapacitated.
Write down the game as empirical values. Tuition costs, but not free.
A prerequisite for the return of a gift would be the so-called "gross ingratitude". But we're still a long way from that here. So nothing should go there anymore.
I assume that your daughter's disability does not affect her ability to work, so she is fully capable of doing business.
Other than getting the police involved, lying and hoping they'll believe they stole it, which it sure won't happen, there are no options. Maybe they are trying to convince you that you want to buy it back and in the end you won't give her the money because, as you said, you still have the packaging and nothing would happen except for her to cry.
But without risking things completely and making yourself liable to prosecution, there are no more ways to get it back.
I don't think that's possible. A gift is a gift.
Unfortunately, this has to be booked under "apprenticeship fees".
