We conveniently had all of our Christmas parties really early this year. This is great news considering we're going to have a baby right around Christmas and it will be very difficult (or impossible) to attend any parties.
Our church already had its Christmas music program, my mom and dad already did their annual Shepherds party (dress up for nativity and "Jerusalem" food), we had a Christmas cookie party at the Bartletts, we've got almost all of our Christmas shopping done, and we went to see the Christmas Carol play at the Hale Theatre (which was incredible!).
I feel like we've had so many Christmas activites already that if we do have to miss Christmas day it will be fine.
