As you might know, in Germany presents are exchanged on Christmas Eve. When I was a child, we spent most of the day at my Grandma's house waiting for the call telling us to come home. My Grandma would watch TV with us, we would play board games and get more nervous and excited from second to second. Actually the afternoon was filled with a TV program called "Waiting for the Christ Child", it showed Christmas movies and shows for children. I'm not sure it really helped and I still feel sorry for my Grandma who had to put up with us.
Now I'm all grown up of course, well, or maybe grown sideways - I'm sure the Christmas feast won't help with that - and much cooler about that. My tradition now is to watch two funny Christmas specials about how Christmas Eve is in two families. They are on my German blog if you want to have a look.
What country do you come from and do you have your own Christmas Eve traditions? Why not tell us about it?
