Apparently this is what my OH thinks. Does everyone just put up with difficult relatives?
DH's DM doesn't want to have her Dsis because she is tedious and bad company. It would "spoil Christmas". Her other siblings and wider family have never asked.
Obviously we do not have to ask this person. DH will though. I have never had a Christmas day I want. I feel sorry for our DC. It is a shit situation, we will make the most of it.
We will have a lovely Christmas Eve and Boxing Day instead.
