I can't believe I forgot to mention the granddaddy of all Christmas books... Dicken's A Christmas Carol. When I first told my students at the homeschool co-op we were going to read it (my last year in the co-op) at first they didn't look very happy. They ended up loving the book and we agreed it was wonderful. Even those who thought his other works a little difficult enjoyed it.
They were surprised when I told them my favorite film version of the book was The Muppets Christmas Carol. Those who had not seen it found a copy to watch during the weeks we studied the book and they all agreed it really was excellent. I think my second favorite is the performance of George C. Scott but I also liked the one that has Jean-Luc Picard (I mean Patrick Stewart).
I'm on the lookout for a few of the movies which have been mentioned that I have not seen before. Once the weather clears up (perhaps in a day or two?). It is absolutely wretched out there now. It sounds like a hurricane instead of a snow storm.
Regarding Merry Christmas... yes, I have friends who are Jewish and Hindu. One thing about living in a college community is the diversity. I have sent Happy Holiday cards to my Jewish friends, unless I took the time to buy a Happy Hanukkah card. Although we've known our Jewish friends for so long they would not be offended getting a Christmas card but I want to show them respect.
