We tell ourselves stories in order to live. - Joan Didion

Nothing was irrevocable; everything was within reach... I could make promises to myself and to other people and there would be all the time in the world to keep them. I could stay up all night and make mistakes, and none of it would count.

"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. "He was on his way home from work — happy, successful, healthy — and then, gone," I read in the account of a psychiatric nurse whose husband was killed in a highway accident. In 1966 I happened to interview many people who had been living in Honolulu on the morning of December 7, 1941; without exception, these people began their accounts of Pearl Harbor by telling me what an "ordinary Sunday morning" it had been. "It was just an ordinary beautiful September day," people still say when asked to describe the morning in New York when American Airlines 11 and United Airlines 175 got flown into the World Trade towers. Even the report of the 9/11 Commission opened on this insistently premonitory and yet still dumbstruck narrative note: "Tuesday, September 11, 2001, dawned temperate and nearly cloudless in the eastern United States.

"I promised myself that I would maintain momentum.
"Maintain momentum" was the imperative that echoed all the way downtown.
In fact I had no idea what would happen if I lost it.
In fact I had no idea what it was."
