He did not think of himself as a tourist; he was a traveler. The difference is partly one of time. Whereas the tourist generally hurries back home at the end of a few weeks or months, the traveler, belonging no more to one place than to the next, moves slowly, over periods of years, from one part of the earth to another.

— Paul Bowles《遮蔽的天空》The Sheltering Sky, 1949
