In most of Arizona, you can't count on nature to really do anything that you'd consider festive for the winter, like, say, snowing. Or getting below 70°. Any festive atmosphere is entirely artificial, brought on through decorations.
I can't be arsed to hang lights outside even on a good year, much less when the house is still under construction, so our house normally doesn't radiate the Christmas spirit out to the neighborhood. But, it got this coat of white primer yesterday, and I'm kind of surprised how much I like it as a seasonal thing. I wish I could have told the painters to just leave it and come back in January to finish the job. (I'm trying to tell them to come back a couple of Januarys later to pick up their check.)
I remarked to the foreign students we host at our house that our house looks like it's all decorated for Christmas, and one of them, the not so great at English one, later asked Becki if we repaint the house to decorate for winter every winter, or just this one.
