As a teenager I hated Christmas. My parents have been divorced since I was 4, so Christmas meant that I had to travel to Mom's family on Christmas Eve then to Dad's family. Christmas Day was awesome until around noon when I had to do the same crap all over again, only this time it was Dad's family first then Mom's.
Now I love Christmas once again, and I think my wife believes I'm crazy. We started a tradition of eating steak and lobster as our Christmas eve dinner. I make a real effort to go to my dad's family on Christmas Eve night, then we go home and feast like kings.
Christmas morning my wife wakes up bright and early around 6:30am and brews a nice pot of coffee, then she makes breakfast which is usually eggs, bacon, sausage, biscuits, and grits. Once again we feast, then we open presents. Now that we have a baby, we're just going to visit the in laws and my mom on Christmas Day which should be done before 2pm.
Christmas Night my wife and I always watch Christmas Vacation an sit by the fire. Nothing fancy, but it's what we do.
