Cities contain a great assortment of people. Whenever I walk around a shopping precinct at midday on a weekend, I am fascinated by all the different types of people hurrying around the shops. Sometimes, I just sit on a public bench and simply watch the variegated streams of shoppers. Today, in the age of globe-trotting transport and communications, city life is more mixed than it has ever been. Capital cities are not cosmopolitan, and eager to attract foreign trade and currency. There is a contemporary English joke which tells that “you can never find an Englishman in London”.
