I would assume that most people here will have vastly different plans for Christmas this year than in other years. According to the news reports, in the UK people are banned from having Christmas dinner together.
My own plans are somewhat normal, but not entirely. We're having a Christmas Eve lunch at a niece's house about 40 miles away. I don't know who all will be there, but it should be fewer than usual.
Our usual holiday meals often include guests who aren't relatives. One guest who has been to Thanksgiving and Christmas dinners with us regularly for years is a guy from one of the Caribbean islands who has lived here since graduating from high school. He does not feel it safe to ever go home again.
One Thanksgiving dinner a few years ago, our guests included a number of college baseball players including one from Canada and two from New York City (my niece is married to a baseball coach). Last year, one of our guests was one of the Lost Boys of Sudan -- one of the most polite and most civilized people I have ever met. Other guests have included local cowboys and cowgirls who had nowhere else to go.
This year, I don't know if we will see so many guests as usual.
Also, one member of the family is in an assisted living facility about 20 miles away from my niece's house. I don't know if she will be there or not. If she leaves the assisted care facility, she will be completely isolated for the next 10 to 14 days. Of course, with there being a number of residents and employees of the combined nursing home and assisted care facility who have covid, they are really under a lot of restrictions now.
