At some point, you should eat sweet mince tarts while reading A Child's Christmas in Wales by Dylan Thomas, then have a quality glass of whiskey by a fire before going for a walk through a pine forest close to the sea. I like Christmas lights, in a Diwali Festival of sorts, and having an excuse to see friends and family. I'm not religious, but where I live, it isn't a religious festival any more, for the great majority of people. You can sidestep the worst commercialism, though there's no escaping the worst xmas music, and just enjoy the gateway to the harsh winter. You have to get winter started to get through it.
We fish people often "get" lighting year round - warm tones, cool tones, what you can do with LEDs, and Christmas lets you take ordinary rooms and use warm lighting to make them extra inviting and cozy. I like coming in from the cold with my poor old dog, and stepping into a warmly but strangely lit room.
