Since we celebrate christmas and thanksgiving at the same time with hubbies family on Thanksgiving, we're free to do christmas with mine.

My brother, his wife and 2 boys, Mom and her freind Harold, my 3 kids, my son in law and 2 granddaughters and hubby and I will be there.
We switch off going to each others homes for supper on Christmas eve and open gifts after we eat. We go to church together at 10 pm.
On Christmas day we spend time at home just relaxing and enjoying our gifts.
This year it's my brothers turn to host our supper. (I've had it the past 2 years) so I'm just bringing a corn casserole and they have to do the lions share of the work. My casserole has gotten to be a staple at our suppers over the years, so I don't mind contributing that.
