I did, however, manage to do something to my second toe (index tow?) on my left foot when sparring with P. I only noticed after the class that I had lost all feeling in it, and it was sort of skewed to the left. It still looks wrong. If it was dislocated or broken presumably it would be a lot more painful, so I'm ignoring it for the time being, but I can feel that there is definitely something odd about it as I walk around.
Getting a good punch in on the counter is a great feeling. There is something immensely satisfying about putting your fist into an opponent's midriff as he comes hurtling towards you. This is one of many reasons for preferring bare-fisted sparring.
