The anwer to your question is that a mirror does exactly the same thing
to all objects, so it really DOES "reverse" your face as well as
letters.
Suppose your friend writes a word on your forehead,
for example the word MIRROR. If your friend wrote big enough, the first
letter M would be over your right eye and the last letter R would be
over your left eye. Now look in a mirror. You would see your face
appearing normal, and the word would seem to be reversed.
The
fact is, however, that your face is reversed also...you are just used
to seeing it in a mirror so it looks normal to you. To convince
yourself of this, pretend the image in the mirror is a stanger looking
at you. You would say that the letter M is over the stranger's left eye
(on the right side as viewed by you) and the letter R is over the right
eye...the reverse of what you know is really true.
Another
way to check this is to hold out your right hand toward the mirror...it
looks like your image is holding out it's left hand. You can never
shake hands with the image in the mirror since they will always hold
out the "opposite" hand you are. This is further proof that the image
is reversed.
Hope this helps.
