Wow. Too bad all the other partyers are still trapped in you-know-whose basement. I just finished taking down the Thanksgiving/Fall decorations and am almost done with my Christmas ones. We can't have a real tree because of the cats, so I bought a small rosemary tree I decorated with expendable ornaments. My good Hallmarks go up on the mantle where beasts can't climb or jump.
