Three days on, I'm still unable to say much about what happened in Barcelona. But I can talk about our enduring special relationship. The city where I got married remains my mistress. The city where I lived a challenging year a decade ago, but to which I return to frequently. Even more so than to Lisbon. The city where I spent most of my parental leave but treated me as a 'guiri' for the first time - having made me feel a foreigner a few times before. The city whose company I missed early last week and said we should visit again soon. Maybe after Christmas.
