There´s nothing special I do for Christmas, simply because the weeks before the 24th (we celebrate in the evening) are the ones with a lot of work at school, and I don´t have much time to do very much at home before my holidays. Next week, one of my colleagues will celebrate her 50th birthday, so something else to prepare for, and less time at home.
In Austria, we´re decorating the Christmas tree on Christmas Eve, which means that I don´t have to do this very soon. We´ll have to buy a tree soon, though.
