I've lived in Israel for 26 years, and for 26 years December 25th (and all the craziness leading up to it) has come and gone and I hardly notice it. If I do notice it, it's to think to myself "wow, December 25th and I hardly noticed it"
This year I'm doing evening work for an American website, writing articles. As I submit each article this last week, I've been writing to the editor who will be reading it "Merry Xmas" because chances are that the copy editor celebrates Xmas.
And I discovered that I enjoy writing that! It makes me feel like I'm enjoying their holiday vicariously, and that I can be a part of it while not being a part of it. Anyway I love where i live but I do like America too (love Americans -- when the copy editors write to me, they're always so polite and pleasant -- LOVE Americans) and get a kick out of being connected.
