Some cities spread, like cancers or B-movie slime monsters, devouring all in their way, absorbing towns and villages, swallowing boroughs and hamlets, transmuting into boundless conurbations. Other cities shrink -- once prosperous areas empty and fail: buildings empty, windows are boarded up, people leave, and sometimes they cannot even tell you why.
Occasionally I idle time away by wondering what cities would be like, were they people. Manhattan is, in my head, fast-talking, untrusting, well-dressed but unshaven. London is huge and confused. Paris is elegant and attractive, older than she looks. San Francisco is crazy, but harmless, and very friendly.
It's a foolish game: cities aren't people.
Cities exist in location, and they exist in time. Cities accumulate their personalities as time goes by. Manhattan remembers when it was unfashionable farmland. Athens remembers the days when there were those who considered themselves Athenians. There are cities that remember being villages. Other cities -- currently bland, devoid of personality -- are prepared to wait until they have history. Few cities are proud: they know that it's all too often a happy accident, a mere geographical fluke that they exist at all -- a wide harbour, a mountain pass, the confluence of two rivers.
