So here's the problem I have.
The teacher says he has no idea why the students are doing what they are doing. So why is he letting it happen? Imagine hooking up with some attractive person who dovetails with whatever your sexual orientation is, and you run your finger down your hook up's arm and they start going, "Aooooogah, Aoooogah, Aoooogah" And you stop touching them but they start rolling on the floor, going , "Oh, baby, don't stop, don't stop, Aoooogah, Aooogah!" Are you going to be, like, "Yeah, baby! You want some more?' waving your hands around in the air and they are going, "Aaaoooooooooooooooogha" (whooops, sorry, mispelled that) Aaaoooooooogah!"
Me, I'd be running, or at least saying, "What the hell are you doing?"
So why does a martial arts teacher not say, "What are you doing? Get up off the floor, you are embarassing yourself and your entire family down to the fifth generation. Your dead grandmother is ashamed she gave birth to your mother who gave birth to you!"
Man, I've been doing this stuff for forty years and sometimes, martial arts are so stupid!
