Like many people the world over I started my Christmas break on a plane. After a few days in London, I was heading back to Denmark to spend Christmas with my family. A week later, I was on another plane. This time to Austria to take up my winter job as a ski instructor. 20 days later, and I am once again in an airport. This time heading to England to continue my studies. As my Austrian colleagues asked me whether I was heading home, I nodded and then shrugged. Actually, I do not really know.
