Dear Groundhog,
Why worry about what they think? Simply, you are not up to dealing all the work that catering for so many people entails. Nor am I. And I don't.
When my sister was alive, we got together on a separate day to celebrate Christmas and exchange presents. I do not invite my parents over on Christmas Day. Their day with us is on Boxing Day. We spread the load. We have energy to make a fuss of them then. Admittedly, that may change, when one of them dies. They enjoy their own day. Christmas Day is for us and our children and grandchildren. I don't enjoy cooking and used to get stressed with Christmas dinner. One year I got upset and admitted how I felt. Everyone was shocked and they sent me into the lounge and took over. They assumed I liked doing it. Now my daughter cooks, which she loves. I happily clear up with the help of the dishwasher.
Tell them you are not up to organising Christmas and ask for suggestions. Give them the chance to rise to the occasion. They may surprise you. I doubt they realise how you feel. If they don't rise to the occasion, tough. Let them sort own their own Christmas. They don't deserve you if they are unpleasant. And decide what you really want to do at Christmas. Best wishes, Ju Ju
I remember my mum getting stressed at Christmas and it upset me. I vowed I would do it differently.
