“On my way up the staircase, I tried to imagine myself coming down this very same staircase tomorrow morning. By then I might be someone else. Did I even like this someone else whom I didn’t yet know and who might not want to say good morning then or have anything to do with me for having brought him to this pass? Or would I remain the exact same person walking up this staircase, with nothing about me changed, and not one of my doubts resolved?”
