Considering the hostile reaction "Merry Christmas" received in some quarters, I'm sure someone will object.
I didn't get any valentines, you insensitive clod!
Hmmmm ... we might change this :-)
And for the rest: one thing I normally do: I never look back - always go ahead.... so be aware of next Christmas ;-)
I'll try to take up the different occasions to build lists of "greetings", but I only can do that for occasions I know - other occasions should be covered by people who know them well.
Ciao, Sabine
