The Nativity. Because it is Christ's birth that we celebrate.
There are certain traditions to Christmas and one is that our tree goes up the day after Thanksgiving. It's just what I do.
If you don't believe, you don't receive.
Last year, one of our family ornaments was a TARDIS.
Every Christmas tree needs a TARDIS as well as a Dalek.
I have kept the tradition of new ornaments and my boys look forward to choosing a new ornament each year.
Because of that ornament tradition, our tree is very eclectic, but it's also very much us. We have dinosaurs on our tree and a pink flamingo. We have world monuments like a pyramid, L'Arc d'Triomphe and Colosseum. We have a star fish and a coke can. And we love it!
