The fact that we aren't allowed to celebrate it in my country. It's seen as unimportant. In fact, we don't ever have Christmas breaks. I saw school buses packed with students heading to class today (and yesterday too), some are even taking exams. Radio stations play absolutely no Christmas music. Nothing in the country is decorated for Christmas. Life goes on as usual as if Christmas doesn't exist.
This video by Gari Sullivan perfectly explains how life is for us. Yes, it's 2 years old already, but I doubt that it's that irrelevant.
