. . . now I'm really confused . . ."Ever notice that when you look in a mirror, right is left, but up isn't down? Why is that?"
When I look in a mirror, left is left, right is right, up is up, and down is down.
Yeah? Then why does the swastika I carved on my forehead go the wrong way, huh? Huh?
This is actually true. Left is left in the mirror and right is right. Try this little test. Look in the mirror and raise your left hand. This is the same hand that raises in the mirror. Remember the mirror world is a "reflection" not a "refraction". If the image was being refracted back to you than up would be down and left would be right.
