I like to celebrate Christmas whether or not I get or give any gifts, but I like to make the decorations, gingerbread, music, etc. And I think the winter solstice should be celebrated, not Dec.25, anyways. Yes you should be happy, but also you should not necessarily be subject to any particular religions, so, do how you like. (It is too commerticalize and other problems how it is done today. They didn't want to play charades or hanafuda or anything, but this is unrelated.)
(P.S. I also very recently made a
Joy to the World music using CsoundMML, a program I had written a few days before.)
