My wife and I had been married for eight years, and things in the bedroom had become predictable. We both felt it, but neither of us said it out loud until we hired Chloe as our babysitter. She was 19, a college freshman who lived a few blocks away, with long blonde hair, bright blue eyes, and a tight little body that she never tried to hide. Short skirts, cropped tops, the kind of confidence that made you look twice. Our kids adored her, and honestly, so did we.
