My wife & I are the old ones in the family nowadays. Parents & grandparents are all gone. We live about 1000 miles from where we grew up, so there's no contact with any of her aunts/uncles anymore since her folks died.
Our son lives in Houston and couldn't come home this year because of work, her older brother lives in Sacramento (about 100 miles away) but he's a drunk and a pot-head and is always too fucked up to drive that far...so once again, it was just us, our daughter, and 3 grandkids for Christmas eve and part of Christmas day. (that's long enough, thank you very much)
In many ways, I miss Christmases of old, when everyone would gather at my grandmother's house (grandparents were long-divorced) for Christmas day and dinner.
No drinking was allowed, (other than a bottle of cheap Manischewitz wine)

so no drunken arguments...although my grandparents STILL argued politics...which is what caused them to divorce in the 1940's.
Christmas eve was always spent with my in-laws...and there was booze aplenty, yet still no drunken brawls or arguments. They had a fully finished basement with a full wet-bar, pool table, and room to dance if you were so inclined.
Since all the old folks have passed, and we've moved to Kahleeforneeya where it doesn't snow, we've both more-or-less lost the Christmas spirit...it just doesn't seem like Christmas anymore.
Sometimes I miss the old days.
