I love the Christmas lights cause winter is soooooo depressing. I wish people would keep them on through the end of February!
Otherwise our holidays are very minimal and low key, cause we're a small family. We don't really do gifts cause we're all trying to minimize, and I Really hate the whole consumer aspect. Mom will probably bake a bit, but I don't. We'll send a few cards out (probably from mom's huge stash), and maybe go to a couple parties, a festival or play or two, and church on Christmas Eve. It's my busy work season and low mood/ energy time of year, so don't really do much.
I do like Christmas music if it's *actually* about the holy family- like Mary Did You Know and such, or quieter things like Sting's On A Winter's Night album. I like some of the Hannukah music too. Often I'll gravitate to instrumental jazz or Gregorian chant- cause the turning inward feeling works with the dark time of year.
Decorations I'll put up Thanksgiving weekend generally. Minimal...no tree cause =^-^=s
I Much prefer Autumn though- with the outdoor festivals, pretty leaves, bonfires, nice weather, and such!
