If you don't like it, don't do it. And don't apologise.
Even I am not rude enough to snarl at everyone who wishes me merry whatever, but I don't get involved. I've found that if I am vague about what I will, or will not, be doing during the festive season the majority of people are too polite or self absorbed to ask too many questions. As for the others, they can mind their own business and those who's opinion matters to me accept that I won't play. Shrieking children, tinsel, false bonhomie. Bloody carols. NO.
I buy presents for my friends and family when I see something I think they would like. Gift giving, for me, is a very random event that doesn't line up with birthdays, Christmas, anniversaries etc.
Prawns in the river with the hound. That will do, Pig. That will do.
