Christmas tradition? Well, while my family does celebrate Christmas, I don't. I do everything they do, just instead of Christmas it's Festivius (I don't remember where I got this. I think it was from sitcom.) cuz I'm Atheist. But we don't really have any traditions. The only one is that we open presents every Christmas morning. For dinner, every year, we have something different so I guess you could call that a tradition by definition but I don't really consider it one since we don't do it on purpose. We just have whatever we feel like.
I guess that's all I have to say...
