At home there's me and 2 young adult sons.
We usually have my parents too. I have a sister who lives away, she's invited us all, but DC will likely be working boxing day so difficult for us to go/they probably won't want to.
DS1 is good company, but he has a gf and will likely spend at least part of the day with her family. Good for him, I'm sure they'll have a lovely time.
At our house it will he hard work. Everyone's nice enough, but not sociable. DS2 shy to the point of rudeness. I make allowances for him because he's suffered significant trauma which has definitely made it worse, but he was always "quiet".
My parents are nice and kind, but there's never been much fun or laughter in them. They'll probably refuse to go to DSis because they "can't" leave me and DS2 after the trauma.
If it was just me, I'd probably gather a group of single friends together and have a bit of a do at mine, but that would be a horrible thing to inflict on DS2. Or I'd go away on my own somewhere, but I also couldn't leave DS2 home alone for Christmas.
So is there anything I can do to liven things up a bit?
