Outline your face on a mirror, and you will find it to be exactly
half the size of your real face. Step back as much as you please, and
the size of that outlined oval will not change: it will remain half
the size of your face (or half the size of whatever part of your body
you are looking at), even as the background scene reflected in the
mirror steadily changes. Importantly, this half-size rule does not
apply to the image of someone else moving about the room. If you sit
still by the mirror, and a friend approaches or moves away, the size
of the person's image in the mirror will grow or shrink as our innate
sense says it should.
