It's MrsMyrthos and me, just like last year. The kids have other things to do, which is fine by us. There are plenty of other days in a year to get together (if Covid allows us to do that) and they know we don't care that much about the festivities.
So we sleep in a bit, I fool around with a Nixie Clock I am building and we play some board games and watch a movie. As I am having two weeks off from work, this is basically what most of the days look like.
On Christmas day, there is a bit more food than usually, so we probably have enough for the next day as well. It is going to be Indian food this time.
