I was watching Stephanie's Taekwondo class last night and one young man was having difficulty. They were practicing a series of strikes, part of which they swung their fist backwards and away in a low arc. The boy was not doing that part correctly so one of the black belts tried to talk him through it. He still wasn't getting it so the black belt guided the boy's arm through the entire series ending with the boy's fist going into the black belt's groin. While the boy was embarrassed he also had this look of comprehension and total understanding. After that, he not only did the strikes correctly, but with a look in his eye that in no uncertain terms told me he was taking out the 'nads. We do so much better when we understand the purpose of our actions, eh?
