Small Thought.  A warning from the divine judge!
Please stop writing Christmas with an XMAS. It is an outrageous abbreviation
It has a bad, unfair, connotation like negative, unknown factor, denial of Christ and even
x rated adult movie.
You can write it with an x,  only, if you are writing in Greek because the X in Xmas
comes from the Greek spelling of Christ.
In English, you should write:  MERRY CHRITMAS.  Viva
