“I'm flummoxed by this unraveling of time, I'm losing my grip on myself. I know that nothing awful will happen on the other side of the door. If anything, I'm about to have a perfectly forgettable day: a class to teach, a meeting with colleagues, maybe a movie. But I'm afraid of forgetting something crucial—my cell phone or my identity card, my health insurance or my keys. And I'm afraid of running into trouble.”
