At a fundraiser, the guest sensei called me up for ukemi. I don't remember the technique, but he wanted me to do joudan tsuki (I think it was something about moving off-line). So, I proceeded to punch at his face for a couple of minutes, thinking it weird that he didn't start doing a technique, and, instead, kept entering and turning. I finally realized, when I heard him repeating "holy smokes", that he had told me to attack differently after a few punches. I looked at my sensei, and saw him indicating ryote dori. I, brain-fried, politely asked to sit aside for a bit.
Needless to say, I'm glad that he's good at moving off-line.
