Humorous in a dark way. And those 'ones' were just virtual apsects of my personality, not necessarily permanent. Regardless, a lot of the kids I see these days, whether fat or skinny, seem to fight less than when I was a kid. This might be a good thing...but it might have a drawback within the topic of the thread. Yes, drills are good, especially when communicated as such. These teacher folk are not drill instructors, so they goofed. And they jumped the chain of command.
BUT, as with anything regarding children, the parents must educate them about these things and how to handle themselves. If they get in a bind and they haven't the gumption, etc, then that's how the ball rolls. I mean, in more violent societies, the parents didn't want to keep around offspring who couldn't handle themselves an all. They only took it personally if they kept producing similar offspring.
Not that I'm advocating those kinds of social conditions. Merely illustrating. Kung fu, is not only moving within the flow, but the ability to discern smoother currents, from a cosmically-functional perspective.
