I never understand why people are so caught up with being obligated to spend special days with all the relatives. I grew up in a migrant family, and never knew my grandparents, so to me it's completely normal to spend days like Christmas with just parents and young children. After I got married (and I migrated to my husband's country), we did a couple of Christmas's with PILs, and then I decided I wanted to do Christmas my way, in my own home, and cook my own dinner. Inlaws are welcome if they want to jump on a plane (obviously not during Covid), but I'm not travelling to them all the time and having Christmas their way every year.
My poor sister used to have to divide her time between 3 sets of grandparents. Absolutely exhausting, and the poor kids never got to have Christmas in their own home, until she eventually put her foot down and decided to have Christmas at home for once.
When did Christmas become all about the grandparents? It used to be all about the children.
