Here are some adapted questions from a medical professional boundaries course. They are good ones to ask yourself if teaching. They are true false questions.
1. A boundary violation occurs any time the instructor becomes more than a teacher of the various aspects of the art of aikido...
They are all true by the way. If you answered any false, you may be at risk.
Well, hell, a whole bunch of us worked under sensei's direction to put a new roof on our dojo. He was the boss because he's also a carpenter and qualified to do (and lead) the job, and he wasn't acting as "a teacher of the various aspects of the art of aikido". Was that a "boundary violation"? Should I be nervous?
