For Thanksgiving we are going to my aunts house for a big extended family meal. It's my father's side of the family that I had no contact with for almost 20 years (long story) so it's nice to be included and feel like I have family.
Dh's mom and my mother are deceased so there isn't any real family for big celebrations like that.
For Christmas, I haven't gotten that far. Who knows what we will do.
