My family (mum and her partner, my sister and half sister and their families) are due to visit and stay with us for a few days over Xmas. We live about 150 miles from them so we alternate spending Christmas in the two places, although we always go out for Christmas dinner. My half sister doesn’t always join us but does sometimes and is this year.
We all agreed on the restaurant for Christmas Day a few months ago and I booked it. My half sister is now saying she can’t afford it and wants us to host Xmas dinner at home. We really don’t want to do that as we look forward to going out for it, not cooking and just relaxing.
I’ve suggested that she comes before or after Xmas for a day or two instead but she thinks that’s unfair and doesn’t see why we can’t just cook dinner at home. My mum is siding with her and it’s causing friction. Are we being unreasonable to not want to change our plans and not want to have to cook dinner ourselves when we were looking forward to going out?
