We visited SIL (DHs sister) this weekend, staying in a hotel in her home town. PIL came over for the day. We went to the cinema and for a meal. For context we have two kids and SIL has a partner but currently lives alone (and was alone when we met) and has no children. DH and his sister are both early 40s and very close in age.
For both the meal and the cinema PIL paid for themselves and SIL, and we picked up the bill for our family. It was done very openly and left DH feeling pissed off. It's not about the money (and no-one attending would struggle to pay for a cinema ticket and pub lunch - though I have been unemployed for two months) but the openly biased treatment.
Unfortunately they do have form. We would probably be non-contact if we didn't have children.
Is DH BU to be peeved? Or should it wash over him? Does anyone else have parents or in-laws who do this kind of thing?
