My brother and I are moved out, but we still do the same things that we have always done for Christmas.
On Christmas eve, we go to the mall in the morning, and do last minute panic shopping as a family.
In the evening, we get a late dinner of Chinese takeout from the same place we always have. Then, when we're ready to go to bed I read "A Visit from St Nicholas" from a brilliantly illustrated hardcover copy. Even though we are both well into our twenties, my brother and i giggle at the funny words like breast, jerk, and threw up, as is tradition.
Then on Christmas morning we get up, open our gifts, and watch the Comeback game. That tradition started when I bought the DVD for my father seven years ago.
