Some days I like explanation.
Some days I like to just watch and emulate.
Whatever sensei does is fine with me...
I agree with Keith. I trust the teacher.
I remember one lesson with Shigenobu Okumura sensei at the Aikikai in Tokyo. He brought in a blackboard and gave us a complex lecture for almost the whole hour of the class. Then as the class ended he didn't want to end it so he continued it through the 30 minute break between classes and into most of the next hour. The students coming in to change for the next lesson did a double-take as they walked past the door and saw us all sitting down quietly. At the time we all complained about our legs going to sleep but we all learned something different and it's a cool memory.
