To read an object requires forgetting oneself a little, to leave room for the past of someone else. Traveling through mirrors, that requires facing up to oneself. One has to have guts, y’know, to look oneself straight in the peepers, see oneself as one really is, plunge into one’s own reflection. Those who close their eyes, those who lie to themselves, those who see themselves as better than they are, they could never do it. So, believe me, it’s no run-of-the-mill thing.
