In one way, at least, our lives really are like movies. The main cast consists of your family and friends. The supporting cast is made up of neighbors, co-workers, teachers, and daily acquaintances. There are also bit players: the supermarket checkout girl with the pretty smile, the friendly bartender at the local watering hole, the guys you work out with at the gym three days a week. And there are thousands of extras—those people who flow through every life like water through a sieve, seen once and never again. The teenager browsing graphic novels at Barnes & Noble, the one you had to slip past (murmuring “Excuse me”) in order to get to the magazines. The woman in the next lane at a stoplight, taking a moment to freshen her lipstick. The mother wiping ice cream off her toddler’s face in a roadside restaurant where you stopped for a quick bite. The vendor who sold you a bag of peanuts at a baseball game.
But sometimes a person who fits none of these categories comes into your life. This is the joker who pops out of the deck at odd intervals over the years, often during a moment of crisis. In the movies this sort of character is known as the fifth business, or the change agent. When he turns up in a film, you know he’s there because the screenwriter put him there. But who is screenwriting our lives? Fate or coincidence? I want to believe it’s the latter.
