not to hijcack the thread from the story. But the dickens' tale introduces a sort of "be a better person to your fellow man." And that's a good thing. But I don't know that its about the real meaning of the season. I think the original Judy Garland lyrics, rather than the updated lyrics for Sinatra who wanted something more light hearted, work for me.
Lyrics to "Have Yourself a Merry Little Christmas" from Meet Me in St. Louis (1944) at Reel Classics
I think the message of the Dicken's movie, relative to the reason for the season, is giving. Happiness is found in the giving to others. The happiest people I know, do this on a regular basis. Bless `em.
