In 2003, stuck in Copenhagen due to a blizzard, I spent a day walking around with a Danish guy I'd met at the airport. He showed me his favourite places, protected me in Christiania, and we talked like old friends. He asked me if I was one of those who like to sit in a cafe by themselves, just watching people pass by.

Back then I thought I wasn't such a person, but now my answer would be a definite "yes".
