People who live in the big city go to theaters, attend the opera,visit museums and picture galleries, browse in bookstores, and shop at Robinson's, Bloomingdales, Marshall Field, or other large department stores.
These activities fill them with culture and sophistication. Also, they crowd into jammed subway trains or buses, squeeze into packed elevators, cross the street in competition with high-powered motorcars, patiently stand in line outside of movie houses, and then wait again in the lobby for seats to be vacated. Also, they have the privilege of spending two hours a day going to and coming from work.
As a result, city-dwellers are refined, polished, courteous-or so the etymology of urbane (from Latin urbs, city)tells us.
So urbane people are gracious, affable, cultivated, suave, tactful-add any similar adjectives you can think of.引自 session 36
