a gift is a gift esp if its not made with a promise (e.g. e-ring)...in a case like this I would not return the earrings. why would he expect to get them back? he gave them to her..they are hers. did he give them to her with a condition that they not break up within a certain period of time? ridiculous.
as greg notes...when you give expensive items as gifts, it's a 'sunk cost'.
I agree with everyone else that she doesn't have to return the earrings. They were given as a gift. Usually, when you give someone a gift, you don't expect them to return them. Maybe your friend should have though about that before buying such an expensive gift?
Although, personally....I might have returned them. If they broke up very shortly after he gave her the earrings, I would personally just not want them anymore. If they were together for a very short time, I would feel a little weird keeping something so expensive from someone who I dated for a short time. But, it's different for everyone.
Bottom line: gifts don't HAVE to be returned. That's the point of giving a gift. You give someone something because you want them to have it, with no strings attached.
I can't believe it would even enter into the guys mind to ask for a *GIFT* back. Really poor form....but then maybe it's the same guy who wants to buy a diamond for his mistress. In that case, get a pre-misnuption.
Expectations are one thing...reality is another. Relationships are give and take. Any relationship. He gave her a gift regardless. A gift is a gift. Dictionary definition:
gift
n.
Something that is bestowed voluntarily and without compensation.
