It depends on which side of the family we are spending Christmas with. Jordan's family doesn't do anything on Christmas eve.
When we spend Christmas in NY, my family gets together with our best friends and we have a huge 7 fish dinner feast. Salmon, mussels, clams, crab cakes, pasta, bread bread and more bread. And oodles of desserts. There are usually 20-25 people and it's SO much fun. We sing-a-long to Christmas songs, and just laugh and drink and enjoy each others company. It's one of my favorite parts of the season and I always miss it SO MUCH when I'm not there for it.
After dinner I go to Midnight Mass at my church with my brother and best friend, and then it's home and to bed.
