Every year, come December, I do the same thing: I greet or say goodbye to people with a cheerful "Merry Christmas." And every year I find the same sad reality: less and less people correspond. (Two people total gave any sort of answer this year.)
The thing is, they don't say anything at all! They either completely ignore what I said, or are so taken aback by the the unexpected greeting, they can't even utter a grunt in response. Clearly, no one else has wished them any form of happy holidays before me, seeming to support what Bill Watterson wrote 20 or so years ago:
"This season gets less and less merry each year."
