“It isnt that you subordinate your ideas to the force of the facts in autobiography but that you construct a sequence of stories to bind up the facts with a persuasive hypothesis that unravels your historys meaning.”
—Philip Roth (b. 1933)
“Many a time I have seen my mother leap up from the dinner table to engage the swarming flies with an improvised punkah, and heard her rejoice and give humble thanks simultaneously that Baltimore was not the sinkhole that Washington was.”
