A pencil is a simple and predictable piece of technology. There's only one way of it working (it will function when it is sharp), and an obvious failure model(too short, too blunt, no lead). With a car, especially the kind of limp-along rust bucket most of us got for our first ride, it's more complex. There's coaxing involved, especially on cold mornings. There's that noise that never amounts to anything but never goes away, random stalls you begin to put down to the cast of the moon. None of it means it's broken, just that it requires friendly attention, that it has needs. Gradually you acquire a ritualized relationship to it, a bond forged by its unpredictability, by the fact it has to be dealt with. Which is how you come to know people, after all: not by things they have in common with everyone else, but through learning your way around their eccentricities, their hard edges and unpredictable softnesses, the things that make them different from everybody else.
