My dd was 21 a few months ago and she was working abroad at the time. She came back home a few days ago and her best friend's mum (my close friend) came round today with some beautiful Tiffany earrings. We were out at the time but she left them on the kitchen counter. When we opened them there was only one earring in the box. The other is definitely not here. We have checked everywhere and it can't have fallen out. It's such a difficult situation now. We've known this friend since dd was 5 and it was such a generous present and so lovely of her to buy them. What should we do? We need to phone to thank her and we don't want to lie to her. That being said, does telling her solve anything? Would you want to know in this situation?
