Merry Christmas to Fitness
But mostly to Sickness.
Merry Christmas to Business
But mostly to Holiness.
Merry Christmas to Joyfulness
But mostly to Loneliness.
Merry Christmas to misses
But also to every mistress.
Merry Christmas to everyone who is religious
But also to those who are superstitious.
Merry Christmas to impulsiveness
But mostly to wiseness.
Thus, Best Wishes for All: I have plentiful.

Only wonder if the etymology might be
'Mary kiss my ... '
Surely not! Forgive my Rudeness!

And so Merry Christmas to Rudeness
But mostly to Forgiveness.
