Obviously, my kindergarten teacher had never been to Rome. The traffic lights play as much a role in regulating drivers as the Queen of England plays in that country's tax system. If the street is clear, you can walk - actually, you should walk, as your chances for crossing the street may be quite limited. But if the traffic light says it's okay to cross the street, pedestrian beware.
People are like Cattle in Italy Well, only when they're moving in large herds, anyway.
Unfortunately, the masses decided to exit the square at once, opting to cross major streets leading to the metro station. Roman drivers were forced to give up the right of way, which to them is an unalienable right, and watch as the herd of people blocked the roads. The drivers created, in their own way, a sort of harmony of horns. Some horns were more high pitched, others had a little more bass. And the more people who crossed the street, horns from further back in the line of cars sounded, almost in rhythm and tune.
