Xmas Eve is the big celebration day for me.
In the morning we invite our adopted dads over for champagnes brunch of lox and bagels
That night We have great food … nibble style (crab, shrimp, good cheese, nice bread, pickled herring, and oysters are generally the fare) champagne , a goody, after dinner drinks, and coffee. We exchange presents, watch the cats ‘open ‘ their stockings filled with catnip and toys. Listen to good Xmas music. And generally just have a a quiet enjoyable evening. (Honestly I think it would be ruined if anyone else was there!)
Xmas day is a bit of a crapshoot… but generally involves going to the dads to have dinner, but usually a small group and exchange a few presents. Some years I’m by myself if DH is working and the the dads dinner is the next day.
On those years, I plan things for me like a good audiobook, or a knitting project, maybe a movie
Plan for some things that are a bit out of the ordinary and seasonal, play it by ear, ask your son and husband what they think… but most of all take time to celebrate (whatever that looks like)
