Just because you're an atheist doesn't mean you can't enjoy some of the ritual, celebration and holidays that go with religion. I'm a firmly grounded atheist but I love Christmas: the decorations, the music, the food, the gift giving, the drinking, etc.

I also like having a little shrine in our house and even get a kick out of buying garlands from the flower lady for Wan Phra. They smell nice. They look nice.
