It’s just a metaphor, but bad things happen when you take your eye off the ball. Like the time I fell putting my pants on, spraining my ankle, distracted by a jogger in a sports-bra glimpsed out the bathroom window; like the woman in Pittsburg who mistakenly poured bleach in her husband’s seven-n-seven contemplating her black eye in a mirror; or like the trucker in Oklahoma reaching for his phone across the seat, plowing head-on into a school bus, killing seven.
