In my gated community neighbors have been putting up their Christmas lights. I myself have a tree in my front yard lit up. Some of my neighbors have very elaborate displays. I've always loved Christmas lights, although I think some houses get over done. But, if you think about it, it's a weird idea. I've tried to learn the origin of the practice and it's come up a dead end. The Christmas tree indoor is rooted in Germany as best as I can tell, where they decorated the tanenbaum for the holidays. That tradition migrated to England in the mid 1800s and from there to America.
But I can't quite figure out where the idea of decorating houses with lights originated. If I figure it out, I will share it here. I guess the thing to do is enjoy the holiday displays and not worry about their origin too much. Snoopy won first place when he decorated his dog house. Good grief. Maybe I'll even start to like icicle lights. Nah.
