Adultery is in most cases a theft in the dark. At such moments almost every woman betrays her husband's innermost secrets; becomes a Delilah who discloses to a stranger, discloses to her lover, the mysteries of her husband's strength or weakness. What seems to me treason is, not that women give themselves, but that a woman is prone, when she does so, to justify herself to herself by uncovering her husband's nakedness, exposing it to the inquisitive and scornful gaze of a stranger.
Stefan Zweig
