I cooked a lot of Thanksgiving dinners during my younger years, but by now at 70 there is NO WAY I am going to cook a turkey just for the two of us. We both think that would be silly. Besides, I don't want to do it, not gonna happen, case closed.
His family usually has an informal get-together and we might drop by to wish everyone a happy holiday, but we never stay for dinner. We have also been invited to Thanksgiving dinner at a friend's house with many of his other friends, which is very kind of him but being a couple of INTJ's, we would just prefer eating lunch at a restaurant on our own like we always do.
Often turkey in a restaurant on Thanksgiving costs a lot, requires reservations, and involves a lot more food than we can or should eat. So, we normally search for a restaurant that is serving something light from their usual menu on Thanksgiving Day. Chinese restaurants are usually very helpful in that respect.
I do NOT want to gain weight over the holidays this year. So I plan to strenuously and actively avoid anything even slightly resembling a feast.
