Because it's Advent, people!
When Travis and I first got married we decided that our Christmas tradition would be to keep the liturgical seasons as best we could. Therefore, right now the only seasonal decorations in the house are generic winter ones and our Advent wreath. On the 3rd Sunday of Advent, Gaudete Sunday, we rejoice by cutting down our own tree, decorating it, getting out the nativity scene and playing the Christmas CDs. But the Wise Men, they're on the other side of the room. We keep the decorations out throughout the Twelve Days of Christmas, which lasts until Epiphany, January 6th. That's when the Wise Men get to the Nativity. It's the weekend after Epiphany that the decorations come down.
Before we did this I always found myself done with Christmas before I even got to Christmas. I was all Yuletided out and the joy, glory and awesome significance of the day didn't matter.
Now, when I'm in the car I will allow myself to listen to 1 Christmas song per trip and I have done my Christmas shopping, but otherwise we're really trying to focus on Advent so that when the real Christmas gets here we can celebrate.
