It is funny how you sometimes come across people who have been living in the same area and you have no memory of seeing this person, and then all of a sudden he steps out of the city scape and becomes alive, as the building where he's living in and the café he's going to, and bit by bit this is the way you construct your own city, ever changing, ever transforming. If Nina would have known John was her neighbour when they met we would never have had the story we know.
