I've taken my little sister and 3 of her friends (all 11) away for a few days as a birthday present to my sister. We're 3 hours away.
One of the girls parents apparently made last minute plans to go away as a family on Sunday, we aren't due back until Monday evening.
I think the girl was supposed to come to my mums house, say why she couldn't come and then go home. But she was there when I arrived to pick them up, with her some of her stuff and didn't say anything so I brought her with us as planned.
I finished work early and the girls were all ready so we left earlier than we were going to, the parents of the girl text me once we had already left saying that she couldn't come. I was driving and my phone got passed back to my sister and her friends to play on and I didn't see the message until we had arrived.
I've now spoken to her parents and they've said they need their dd back home to take her away and that they can't come and collect her. This means me driving them home a day early, cutting the trip short for my sister and the rest of her friends and losing the money I've spent on the extra day. My mum has offered to look after their dd for the week they're away, the girl is happy for this to happen.
Obviously her parents are welcome to come and pick her up but I don't want to have to drive her home early as I'm not sure this is my fault.
WIBU to say no?
