...Rob's comment may have been borderline ribaldry, but O-Sensei's known comment about rice-paper doors probably had more to do with Misogi and the sexual function of breathing exercises in Misogi than it does with kindness.
I thought it was irony at its best! And from what I've been told, we of the male gender do tend to be kinder after, well, "ki breathing exercises." So maybe there's the missing link to this thread...
