Every childhood has its own geography and every child is an explorer, as daring as any Peary or Amundsen or Scott. I was the mildest of children, such a picky eater that my parents called me a “quince” (a fruit sour enough, they insisted, to make your face pucker, as mine did when challenged by any food out of the ordinary). I was neither a daredevil nor a chance-taker, and by my teens scorned myself for being so boringly on the straight and narrow. I never raced a car, or mocked a cop, or lit out for the territories.
