My favorite thing about Christmas is the giant feast...mostly the fresh baked buns sopping up a pile of mash potatoes and gravy!
There is a tradition when we go to my parent's place for Christmas. My mom always tells us we can only open one gift on Christmas eve but I nag and push until we open them all that night. It happens every year since as far back as I remember. I think she fights me and my brothers about it every year for the sake of tradition.
We used to have an old Catholic French Canadian tradition when my whole family was still catholic (we have some who have converted now) called Revellion. My grandparents, uncles, aunts, everyone would get together for midnight mass, then come back home to a giant feast...Essentially turkey or ham dinner at 1:00 am! Because of the late night church and feast, by the time it was all taken care of we would all open gifts because it was Christmas morning. This is one of my fondest Christmas memories and wish we still did it because it's just so off-beat!
