From the opening chapter of The Year of Magical Thinking.
Life changes in the instant.
The ordinary instant.
At some point, in the interest of remembering what seemed most striking about what happened, I considered adding those words, “the ordinary instant.” I saw immediately that there would be no need to add the word “ordinary,” because there would be no forgetting it: the word never left my mind. It was in fact the ordinary nature of everything preceding the event that prevented me from truly believing it had happened, absorbing it, incorporating it, getting past it. I recognize now that there was nothing unusual in this: confronted with sudden disaster, we all focus on how unremarkable the circumstances were in which the unthinkable occurred, the clear blue sky from which the plane fell, the routine errand that ended on the shoulder with the car in flames, the swings where the children were playing as usual when the rattlesnake struck from the ivy.
