We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
Most of my lights come down after Epiphany but I keep two small deer figures at the front door and a small tree on the back deck illuminated with white LEDs on timers.
As we are way out in the Ottawa Valley countryside and the back deck and garden are surrounded by forest, it's nice to have some ambient white light out there at night, particularly when there has been a lot of snowfall.
I'll keep these lights going until mid-March or so.
When I walk the dogs around Christmas time, I arrange my path to go on blocks that have a lot of Christmas lights. Like you, I would like having them on as long as possible, but it seems that most lights are down two weeks after Christmas- isn't Epiphany around Jan 6?
Life is short...don't worry, be happy and play, play, play (with your sparkly lights and other toys), Every moment of delight brings down your cortisol levels so then you live longer and now...life is long! Ergo...those lights are keeping you alive longer!
