It is so neat to read about everyone's Christmas Eve traditions. One Christmas Eve tradition my family has is that we eat pizza for dinner on Christmas Eve. We've been doing that since I was a kid. My mother started that tradition when we were young to save herself some time, since it was such a busy night (plus, it was a treat for us kids, as we hardly ever had a chance to have pizza any other time of the year!)
We still continue the tradition and its probably one of the things I look forward to the most.
