We are not in the UK. So we offered to have elderly in laws last minute as SIL changed her plans.
We get on OK they are of a different era in their outlook on life so I don't fully relax around them but respect them. They worked hard their whole life and MIL is controlled a lot by FIL.
Anyway SIL was to go for dinner to their house. We have alternated with BIL and wife. Their own daughter doesn't bother much with them other than phonecalls. But of course it's covid issue too so I get it.
However dh mentioned SIL is dropping off presents but not coming in. So I put two and two together she has cancelled christmas with them.
The thing is she didn't tell us so mil and fil would be alone. So now we have offered and MIL can't make that decision alone.
It's fine to have them but I am so annoyed. Of course I will treat them well but it wasn't the plan. I am selfish I know but they are dh family and I do a the work all the time and they will comment 'not too much not too rich' and conversation which I find rude. When we went to theirs years ago no crackers and the centrepiece was a packet of bisto gravy no toasties or anything so their Christmas expectations are totally different.
