"I have never learned how to arrange my face into that blank expression of competent invisibility that is so useful when traveling in dangerous, foreign places. You know--that super-relaxed, totally-in-charge expression which makes you look like you belong there, anywhere, everywhere, even in the middle of a riot in Jakarta. Oh, no. When I don't know what I'm doing, I look like I don't know what I'm doing. When I'm excited or nervous, I look excited or nervous. And when I am lost, which is frequently,I look lost. My face is a transparent transmitter of my every thought. As David once put it, "You have the opposite of poker face. You have, like . . . miniature golf face."
