My MIL has no-one else to go to on Xmas day so feel obliged to invite her over, which is fine, except that she has now announced that she is due to work from 11-4 on Xmas day.
On the one hand I feel sorry for her that she has to work on Xmas but it annoys me that it puts our whole day out now.
We had planned a nice morning with just the three of us, MIL and BIL over for lunch at 1.00 and then out to visit friends. At 6 we were going to have FIL and partner over for nibbles etc.
BUT ... if she only comes over at 4.15 we cant eat until then so the visit to friends would be cancelled and nibbles too, as our dd (11 months) goes to bed at 7 ish.
So... AIBU to tell her that she can come over for nibbles etc but that we will be keeping to our day as we originally planned?
