Mrs. and Mr. Scrooge here...our lights are actually turned off at Halloween, Thanksgiving, Christmas and New Year's Eve to prevent undesired guest from knocking (just to put things into perspective, receiving an invitation for Christmas this year set us in panic mode). I used to build a full size nativity scene well into my thirties but a number of tragic family events conveniently happening around the festivities kind of drained the excitement from the whole thing.
In order to compensate, our neighbor keeps his Christmas tree and lights on all year round. He only switched the damned thing off for a week (it was soon after Mrs. Scrooge thinks he overheard her talking to our other neighbor about his ever-lighted Christmas tree) only to light it back on brighter and more colorful than ever!
