There is one man in my dojo who has had some sort of injury. Every time someone does a technique, he grimaces and sighs in pain. He won't tell anyone what his injury is (I think it may be shoulder), but rather, will just shake his head, say it is nothing, and shoulder the pain (couldn't think of another expression
). The thing is, he is also the one who resists technique most (not because of pain or fear, but to try to teach his partners), so no matter how slow you go with him, he ends up trying to make you force technique (which I don't). I am very afraid of hurting him, and try to avoid being partnered with him whenever I can. I take proper precautions to keep him from getting hurt--i.e. going slow, making sure that he's all right, not fighting his resistance--but I'm still afraid of hurting him.
