In my country (a far-off and magical land known as New Zealand), we celebrate by frolicking in the warm, beautiful sunshine, and going to the beach and having a jolly old good time. At least, that's what the "normal" people do. Internet addicts such as myself hiss at the sunlight so we're going to be staying inside most of the time.
So no, I shall not be Paint.NET-ing or Photoshopping a Christmas hat onto my avatar.
I will, however, be completely replacing my avatar with this:
Merry frakkin' Christmas from New Zealand.
