To tell you the truth, I am not much of a fan of it. When I first moved to the US I thought it was cheer crazyness how much energy is being wasted that way. Really people? Here I am hanging every load of laundry to cause less of a carbon footprint and folks are just going nuts with holiday lights.
DH doesn't go overboard like that. Still it's wasted energy in my mind but at least we agreed to upgrade to the energy saving LED type lighting last year.
Are they adorable or what?
