But if you do use a mirror, be prepared to struggle when it comes time 
to teach the next generation how to do it.  You will have to both stand 
in front of the mirror, you in back, as you narrate and demonstrate.

And yet it is a common scene in movies where the wife/girlfriend/mom 
helps a young gentleman with a tie, while facing them!  They must have 
different preperation.
