I'll try to make this as short as possible. Dd at uni, has friend not at uni but lives in home town and they go out socialising when dd is home. Dh owed friend £30 which had been agreed to pay back before certain date. In the meantime daughter had a night out with friend who had brought another friend along who dd didn't know. At the beginning of night out dds friend lost her purse so therefore no money. Friend she brought along had no money at all so therefore my dd bought all their drinks for the night which cost her about £40.(This was separate from the cost of her own drinks) Dds friend hadn't wanted the £30 my dd owed her back at this time as she wanted it in a week or so when she knew she needed it.
The thing is now dds friend keeps reminding dd about £30 due next week, but is this right, bearing in mind dd spent £40 on drinks for friend and friends friend. Dd is torn, she owes it but at the same time she thinks friend owes her. It would really have been better if dd had lent friend drinks money.
Who is being unreasonable here?
