Re: How serious a teacher are you?
Counterpoint: I found that these times (when Sensei chose techniques he was interested in) were among those where I learned most. I'm not sure why.
My guess: You are an advanced student, so you could follow. Sensei was better motivated when picking techniques of his intrest. (The conclusion of this, though, would be that he is less motivated when explaining ordinary techniques. Iīm afraid, that in turn would be my point of routine entering because of model fulfillment lessons.) (PS: Just a thought, I do not know your Sensei, and I donīt mean to be disrespectful)
