“I know it's not strictly sex that accounts for my straying the motive usually attributed to men. I think it's just too tempting to have two lives rather than one. Some people think that too much travel begets infidelity: Separation and opportunity test the bonds of love. I think it's more likely that people who hate to make choices to settle on one thing or another are attracted to travel. Travel doesn't beget a double life. The appeal of the double life begets travel.”
