““It’s my earliest memory: arranging my brother’s marbles into words. It is summer, and I am beneath the oak that stands in the back corner of the work yard. Thomas, ten, whom I love above all the others, has taught me nine words: SARAH, GIRL, BOY, GO, STOP, JUMP, RUN, UP, DOWN. He has written them on a parchment and given me a pouch of forty-eight glass marbles with which to spell them out, enough to shape two words at a time.””
