Well, ex-jehooplas, here it is. Thee Big Day. No, not Armageddon! Christmas. The major Pagan extravaganza. lol
Take another deep breath. Everything will be fine. You are not going to get struck by lightning for hanging a wreath or saying a toast.
You know what? Lots of things are done today because of some extinct ritual from generations past. It's a normal part of human behavior. For example, have you ever noticed men's shirts and pants have a useless little loop on them? I heard those were originally added for hauling dead soldiers. I'm too lazy to look it up, but my point is, this is how traditions develop--from superstitions, practicality, etc.--and then they stick because they're fashionable, fun, or whatever.
So Christmas. Yes we kept Yule logs, trees and New Year's Eve noisemakers long after we abandoned the superstitions that started them. This is perfectly fine and harmless.
Enjoy whatever you feel like doing today, and don't get too down on yourself for whatever choices you make. The sun will rise tomorrow just like it always does. Your monumental choice to celebrate any part of Christmas today is only monumental in your own mind.
Right now I am sitting by the fire, with a nice scented candle, drinking a warm spiced drink, eating some delicious leftovers and listening to Rod Stewart sing Christmas songs. Sublime and enjoyable. See? No bolts of lightning.
