What do you say at Christmas to those you know.

If I know what they celebrate then I wish then a Happy "xyz". If I dont then I wish them Happy Holidays which covers them all...not everyone has a religious holiday this timr of year. Thats fine, but if I dont know...then Happy Holidays covers the ones people do have. Even if I know the holiday they celebrate, Happy Holidays also covers New Years too... lets be honest we all like to abreviate things. Happy Holidays is two words...Happy "xyz" and Happy New Year is 6 words.
