I've taken Dd and some of her friends(10-12) away for the week. Unfortunately I've had family emergency come up today and am going to have to leave tomorrow to help. Dsd (23) and her bf have offered to come and take over. The girls all seen more than happy with this, they have an event on Thursday which was the whole reason for the trip and want to stay.
I've called the other parents to let them know and one parent was furious and said that they don't want someone else looking after their child and that I need to either stay or bring their child home.
I've said they are welcome to come and get their child (4hour drive) and I'm happy to arrange and pay to send her home on public transport but I can't stay or bring her home so if not she will come home Friday as planned. They are now threatening to call the police saying its kidnap and endangerment and I've changed the terms they agreed to send their child on.
Have I do a anything wrong? Am I being unreasonable?
