You must be kidding.  Mirrors do not reflect left/right.  Mirrors simply
reflect light at angles (nearly) equal to the incident angle of that
light.  You perceive it that way because of your gravitational bias.
Stand on the wall and you'll be saying instead, "Why do mirrors
reflect up/down and not left/right", assuming you do not rename directions
because of your new perspective.  I suppose one would be less likely to
think this way if one had only one eye, but it's hard for me to say.
