NC for this as it might be outing. We have recently bought annual passes to a well known theme park and alongside these we get tickets for £15 friends and family entry. The entry price is over £50 usually. We had plans to go this weekend and both of my children want to take friends. Now I think its rude to ask parents to pay if you invite their child somewhere but I don't want to have to pay £30 for their friends either. I can afford to, it's the principle of it as with the exception of one of DS's friends we do a lot of outings and pay for them and they are never reciprocated. Also, we bought annual passes to save money!
The day after the children finish school DD is taking a group of 3 friends, they will pay for themselves as they organised it themselves, they just need me to transport them and on site in case of problems so I think this is different and have no qualms expecting them to pay their own way.
Do you pay for other children if you invite them on a day out and AIBU just to say no to this weekend? I work 60 hours a week and quite frankly can't be arsed to supervise an extra two children who aren't my own as well as pay for them!
