Interesting question. I live in Belgium and... well first of all I don't care for Christmas. I do like to celebrate with family and friends but the religious celebration itself, no. Second I never actually considered it. I do love snow and ice. I recently took on ice skating and... even though I also love the Summer where I can roller blade and skate, knowing that something else is coming is a genuine joy.

So... I can't speak for others but I absolutely love the Winter, from hot chocolate to waffle outside to ice skating, hikes in the snow then relaxing by the file place, there is just so much to look for during that season that ... never dreamt of "a green Christmas".

Edit: I actually had one last year, going to Madeiras, Portuguese island West of Morocco, North of Africa, and... that was fine too. Honestly truth is I don't really care where and how as long as we share a good time.
