When my youngest was a kid he wanted to do martial arts. We go to a Russian self defense dojo. Forget what they call Russian style martial art.
They let me watch a session only because I was deciding whether he should train with them or not. If I did they would not let me watch any more sessions. I wondered about that it seemed not right to me.
Then the sensi did a move with his assistant. He forgot he had his watch on. He cut his assistants face.
I saw that I said forget it and we left. If that would have happened to a kid what lie would they tell that it wasn't anyone's fault.
