Lewis Carol's book was entitled "Through the Looking-Glass", but that was not about looking in a mirror, that was about traveling through a mirror...

Mirror images are chiral, Chiral...

Mirror images are chiral

Not all of them!

Something is chiral iff it is not identical to its mirror image. So a screw is chiral, because its mirror image would need to be turned the opposite way (reverse threaded), while a golf tee would be achiral, being indistinguishable from its own mirror image.  (It gets even more complicated if we start thinking about dynamic systems, but I'll leave it at that for now!)
