There was rarely an obvious branching point in a person's life. People changed slowly, over time. You didn't take one step, then find yourself in a completely new location. You first took a little step off the path to avoid some rocks. For a while, you walked alongside the path, but then you wandered out a little way to step on softer soil. Then you stopped paying attention as you drifted farther and farther away. Finally, you found yourself in the wrong city, wondering why the signs on the roadway hadn't led you better.
