Actually I have heard it,Merry Christmas, more this year than in past years.People are incensed at being forced to call is a holiday instead of Christmas and are revolting,IMHO.
Guess I'm one of the non-PC holdouts about "Merry Christmas".
Beginning shortly after the Thanksgiving leftovers have been depleted I'm layin' Christmas greeting on everybody I meet.
I'll admit that it does pucker up some faces but the number of that response type's been dropping off.
...or maybe I'm just ignoring the liberals better with my old age.
