This is how I met Bob,a very strange person.He was thin as a wire and balding,wore old-style glasses,and always dressed in the same dirty,shabby gray suit,all of which gave him the air of a man who had escaped from a silent film.
He sold encyclopedias and dictionaries in a department store and took cash payments for other less costly books.I became one of Bob’ clients because it proved to be a convenient arrangement:I would ask him for a certain book by a certain author and a few days later Bob would show up,always reliable,with the book in question and at the same price as at the local bookstore.
It didn’t take me long to figure out that Bob was not only exact in the way he looked,but also in the way he moved and talked.The vocabulary he used was strange:when speaking of Juan Pérez,our nation’s president,he referred to Chief What’s-His-Name.He didn’t use “the sidewalk”,but rather “the public walkway”.He never said,“I don’t know”; it was always,“I’m unaware”.He didn’t ride on “the underground rail”,“microbuses” or “trains”; instead he traveled on “the public passenger transportation system”.
