" But this thing that almost never was still beckons, I wanted to tell him. They can never undo it, never unwrite it, never unlive it, or relive it—it's just stuck there like a vision of fireflies on a summer field toward evening that keeps saying, You could have had this instead. But going back is false. Moving ahead is false. Looking the other way is false. Trying to redress all that is false turns out to be just as false.

Their life is like a garbled echo buried for all time in a sealed Mithraic chamber. "
