My holiday in a mystery European city was turning into a disaster. When I asked “where am I?” people thought I was joking and refused to answer. The road layout kept on changing, and the students who were hosting me were starting to get irritated by my phone calls asking them to find me and bring me back to their home.

At last it was time to return home. But I couldn’t remember if I was travelling by train or plane. I kept asking my hosts but they were distracted with “more important stuff”. By now I had lost my phone, my suitcase, had no money and was wandering the streets. Eventually, and completely accidentally, I found my way back to the apartment block, only to discover that everyone had been evicted and the building was being demolished. No wonder my hosts had been distracted – now we were all homeless.
