In an ordinary mirror your right eye stares at your right eye and your left eye at your left eye--the opposite of the right-left, left-right connection we employ for assessing one another in the wild. The image in a True Mirror (which shows what you look like to others) can come as something of a shock. You tend to look the way you do in photographs, which for many people is also a shock. (This is the flip side (反面) of the start you sometimes get when looking at the reflected image of someone you are accustomed to seeing in person.) A newspaper headline held up to a True Mirror doesn't appear backward--it reads just fine. But your own face may seem oddly asymmetrical. Facial mannerisms nurtured in front of a normal mirror may in a True Mirror be revealed in a different light. 'It is a wholly new view for many,' the True Mirror's promotional literature concedes, 'and not surprisingly, some don't like or feel uncomfortable with the new look.' Another issue: in a True Mirror you seem to have far less control over the figure in the glass than you do in a normal mirror. If you turn to the right in front of a normal mirror, the image turns with you and ends up facing in the same direction, completing the visual palindrome (回文). In a True Mirror the image faces the other way, as if you were about to begin pacing off for a duel with yourself and when you take a step, the image steps away from you. In a normal mirror your reflected finger comes out to meet your real one until they touch, like Michelangelo's God and Adam. In a True Mirror the reflected finger comes at you from the other side of the glass, as if pointed by the other hand. Ordinarily, you have no difficulty looking at a normal mirror and guiding your hand to an object reflected in it. Try this with a True Mirror, and your grasp will prove errant. Shaving becomes a blood sport. If all the review mirrors in America's cars were suddenly replaced by True Mirrors, there could be a very special episode of ER (美国电视剧《急诊室》).
