So DH is one of 3, DH, BIL and SIL.
BIL hosts my in-laws 1 out of 3 Christmases. SIL hasn't hosted them for the last 20 years that she has had kids, preferring to spend Christmas as a nuclear family unit and not inviting anyone other than the 5 of them. Which is fair enough but has meant we have hosted the in-laws 2 out of 3 Christmases along with my parents. My in-laws are very welcome and we love to have them, them and my parents get along well and we all have a great time.
This year SIL is going through a divorce, and invited herself to the in-laws. We have extended the invite to her and any of her now adult children that wish to join for dinner and I have
already ordered a large turkey to accommodate.
However SIL has now asked for the in-laws to cook for her and her "kids" (adults). She thinks one of her sons (who she hasn't actually spoken to for the last 3 months so is 2nd hand through another son) will only come if they don't have to come to ours for lunch as they don't want to hang out with my family! Not only offended but think son attending is pretty unlikely anyway given they aren't speaking to SIL.
In laws are going along with this ridiculousness because SIL has had a hard year. But they are now now trying to get us to give up our Boxing Day pyjama day to do a second Christmas with them. I don't want to go there. I'll be tired after running around at Christmas hosting my parents and want to hang out with my young DC and their toys.
I obviously will be gracious and won't argue about this as I love my in-laws but AIBU to be annoyed about this situation?
Also WIBU to say that's fine they are hosting SIL for Christmas but refuse to give up my Boxing Day just because they don't feel they can say no to SIL?
