after I had performed the pivot he would bump me off balance with his hip. I have done this to beginners in aikido to demonstrate that they are too close to uke after their pivot, but no matter the distance I put between me and this higher-ranked aikidoka he continued to bump me off balance. Finally, in the course of demonstrating to me what was "wrong" with my technique, he had me grab him. Of course, I could bump him off balance too, which, out of respect, I did gently. When he realized that I could do to him as he had done to me, he then began to lead me forward out of the tai-no-henka position (and out of position to bump him).
Old age and treachery will always overcome youth and skill.
Anyway, I was thinking...should we be able to "bump" each other off balance after performing the pivot? I think I'll explore that in class this week. I want to become UN-BUMPABLE baby!
