Well, I figure my sisters will keep me up most of the night as we all sleep in one room on Christmas (tradition) and despite the fact that we are now 37, 34, 29, and 27 (plus a 38 year old wife) we will probably act like 7 year olds and spend half the night talking until my dad comes in and tells us to stfu. Then we will fall asleep and wake up to see that Santa Claus brought presents. Yay for the jolly, red suited, fat man.
Then after opening said gifts we will all trek to Waffle House (tradition again) where I will consume multiple eggs and probably some shitty bacon. Later in the day I'll probably cook turkey and things that go with turkey including stuffing and mashed potatoes, oh, and roasted potatoes too. Then I will eat the food (though probably not the stuffing...so I will stay primal if you include potatoes).
Then we will all sit around groaning and watch Christmas Story. Hopefully no one shoots their eye out.
