Writing is, among other things, an attempt to make sense of the world. To find meaning, or at least patterns.

"How many times, in class, to students, to writers, have I said: Don't tell me the story in a straight line. Break the grid. Steer your way toward wisdom by scrambling the sequence of facts."
She goes on to quote Abigail Thomas on the pitfalls of chronology, in a blog post worth reading.
