Cities are contrived by big men with black pens and coattails, to streamline life. They move at the pace of trains, cars, buses, bikes, and taxi cabs. Late business people clutch stuffed briefcases to their chests and shield against the driving crowd. The hurried stream of people forces the pace to quicken under their rushed step. Cities assume an attention span no longer than the pause at a traffic light or a momentary glance into a passing window.
