Decorating for Christmas? When I was growing up, the outside lights would go up within a week after Thanksgiving. It started as Dad's job, then got transferred to me. I was much more anal about not having two of the same color bulb in sequence, with one exception being the year I put a sequence of red bulbs over our front door. Mom didn't care for that, and made me change it.
Inside, there was the creche and other holiday decorations that would go up around the first week of December. The tree itself wouldn't go up until about a week before the big day, because Mom didn't want it drying out too early.
Der B and I didn't bother with decorating back in Long Beach. Last year, our first here in Rehoboth Beach, we finally decided to get a tree on the chance that the grandlads would come down to visit and wonder where our tree might be. They didn't visit. That, and we learned the hard way that having decorations too close to the floor wasn't very wise in a dog-inhabited house.
This year, if we get a tree at all, it will go up in the den, not the living room, because the dogs love having the living room window free for their street-gazing. Outside lights are another matter. We've got the lights, and the hooks...and a ladder that is too danged short to easily reach the roofline. My fear of falling is going to be a real problem with getting those lights hung.
But there's always the chance I'll be able to sequence those lights above the front door....
