Re: What's in a name? sensei, shihan, etc.
I call my instructor Nick off the mat, and sir while on. Works for him.
I call my judo coaches/instructorsBob& Ray/Raymond.
My respect for them is obvious, and even lacking an honorfic, which they ask that people don't use anyway, the respect is obvious.
There's a certain cynicism about the need for "titles" I think, at least in the part of the States where I grew into adulthood, if one can call what I am now an adult. My wife sometimes calls that into question.
Still, I had no problem referring to Professor Yoji Kondo (astrophysics, as well as aikido and judo) as Sensei. HE didn't want the Shihan tag, either.
