I did not interact (at least not enough) with Sensei Fariborz till I got my Red belt.
I was cautious not to say or do anything to offend him. It was the initial nervousness but after attending the first couple of classes, I feel at home interacting with Sensei. I try to observe and absorb from Sensei when I can. When we line up for the class, at times I have sensed that he is not happy when people lined up on the mat are still talking, but he keeps his calm and composure. He would not even talk about it during/ after the class. I try to do the same when driving on the road and my kids drive me crazy.
When he teaches the class and if he senses that I am doing that particular technique well, he would give more tips on how to do it better. So it is not a cookie cutter class with Sensei. It is a progressive class without anyone even realizing it. Sometimes I feel that I have missed his classes during the earlier belts.
