This is really not a massive issue but I wonder what the consensus would be.
DD, 16, has an evening out arranged. It's on the calendar and has been for a number of weeks.
We have just found that we can go away camping that night. The weather will be fab (apparently) and it'll be fun for all of the family.
WIBU to take everyone camping and have her miss this pre-arranged evening? She'll be furious if we do (and if the weather's rubbish I'll never live it down)
