There are days when that dark face is something I can think of as a friend – a primal energy that carries me forward when nothing else will – but more often than not I am face-to-face with a stranger, a companion to something I recognise as myself, sure enough, but one who knows more than I do, thinks less of danger and propriety than I ever have or will, feels a cool and amused contempt for the rules and rituals by which I live, the duties I too readily accept, the compromises I too willingly allow (p. 262)
