[b]I don't see anything wrong with that. If you come up against a teacher who isn't shy in putting their fist into your face, are you going to keep getting hit, day in and day out?
I agree with Jun on this one. Just last week I was making a grab for my Sensei's hand so he could demonstrate a sokumen. Instead of doing it in a manner that would have led into a pure throw, as he did with the previous two ukes, his arm rose very quickly and went strait towards my nose. Since I was moving at full speed, the only way to avoid it was to throw my head and upper body back which caused my legs to fly up. Did I throw myself? Yes, but the alternative would have been getting hit in the face which probably would have knocked me down anyway. Trust me, it wasn't a difficult choice.
