The metro is not a place of synchrony, despite the regularity of the schedules: each one interpretes its own definition of what a space is or is not. Spaces are never what they're meant to be. Inside these places, individuals manage their own space and their own time. They are clever when they have to encounter other individuals, they adapt to the spaces and create new ones with their automatic movements. They know where to stand and where to wait. They also know, by an unexplainable instinct, how to move and how to act. Therefore, subconsciously, they know how to build new places.
