Hi, I have a bit of a quandry - one of our kids is an adult living with their partner. I'd like to take them to a theme park this summer with the rest of the family. I intend buying a ticket for our grown up son but do I pay for his partner's ticket too? My husband says they should pay for themselves, and I think we should pay. Our son is on a low wage which is why I think it should be our treat. Opinions welcome ☺
