Well, lord knows it works well enough for my own teacher. Let me put it to you this way…I take group classes, and every 8 weeks we have a “graduation” of sorts. One time oe of the women in the class convinced us all, including the teacher, to go out for a drink afterward. When he announced that he was about to move in with his girlfriend, ALL the women (except me and my buddy - we’re in it for the music, dammit!) dropped the class. It was hilarious.
And don’t get me started on what happens to my hormone levels when he describes in class the precise technique for running the fingers up the neck…
Yeah, my little brother ain’t stupid.
