Namely that someone who thinks the way you do/did (you mentioned it elsewhere too and it was quite telling that you didn't know what unbendable arm was at all) about the exercises is going to be far more impressed when they see the real thing than someone else might. That was all.
Yep, nice little dig there. I don't know much, so therefore what I see will impress me. Kind of funny, really. Because in that, you have lumped together quite a few of us: Ron, Mark C., Murray M., Rob L., Erik, etc, etc, etc. And we all have backgrounds in more than just aikido. But hey, what do we know? We're easily impressed because of how we think and what we don't know. Or perhaps, it was just me? I was more impressed than the others because I don't know much. Well, shoot, why not just ask all the others how impressed they were? Heh, and good luck with that. I've already talked and met quite a few of them. I know the answers. I know the backgrounds. And I'm in good company.
