Actually, it's not Christmas. It's December 6, the Feast of St. Nicholas. Tomorrow is December 7, Pearl Harbor Day. Christmas is December 25 (or after dark December 24, if you're in a hurry!).
i figured that it was referencing something specific to which I was not referring. I just meant in general, anyone who gives me a general "happy holidays" gets a very specific "merry christmas" in return.
