There are times when you wander around a foreign city you barely know. You are not wandering aimlessly. You are looking for a place to sit. Open doors, welcoming faces - nothing seems good enough, and it's getting darker by the second. Until, hungry and exhausted, you suddenly realise that all along - you've been looking for a particular place. One that you loved all those years back and one that, quite simply, doesn't exist in a foreign city you barely know.
