Originally posted by Hugh GlassBecause to read something that isn't facing you but is facing someone else you need to rotate it along a vertical axis - because all people have the same "up" but not the same "left".
When you look in a mirror, the words are running backwards, but not upside down?

To further illustrate the issue - mirrors CAN make the text appear up-side down. Take your book, and rather than turning it around on the horizontal axis toward the mirror, flip it upside down to face the mirror. Now, suddently, it's upside down but still correctly running left to right.
