I grew up in a split-faith household, with the more zealous side not celebrating common religious holidays, so I skipped on quite a lot of Christmas drama, though still got my fair share of it on other occasions, and of course I witness other people suffering through it. One Christmas Eve, an acquaintance asked me out of the blue if he can crash at my place for the night. Turns out, he wanted to skip the "Christmas spirit" experience and learned from our common friend that my apartment is a Christmas-free sanctuary.
My wife came from a Catholic family. We have small children now, and still struggle with deciding whether or not we'll be doing the whole Christmas thing. On the one hand, we don't want to deprive our children of the tradition almost everyone else in the country shares. On the other hand, my wife enjoyed the full course of almost two decades of family holidays, and even more than me wants to spare our children the "Christmas atmosphere".
