My old instructor had a saying,"there are no sorries here'. If we said we were sorry we would be doing pushups. I think it may have been a bit extreme,but maybe not? He hasn't been teaching for a few years and my current instructor who was also under him still says 'no sorries',but he has the 'ju'(soft) quality,sometimes a little too 'ju'.
Accidents do happen in class,but we all know why we are there and the risks involved. We are there to learn and to take care of eachother at the same time. So should we be sorry? If I'm sparing and I throw a jab that catchs someone as they are charging in should I say sorry?
I think there's a happy medium somewhere?
The2nd ammendment, it makes all the others possible. <///<
