knocking sense into a person!

[1kickKO]

Well if the student is just asking how a technique is done, by all means help him/her out with that technique.

 

But if it is one of those nagging "you don't do it like that" types...simply talk to them after class, or pull them off to the side and tell them that as nicely as you can, that sensei appointed you to instruct, and that you are doing it how sensei showed you, and that if they really don't like it they can ask sensei on the matter but please don't bring it up in front of class, as that's disrupting class time.

Do a demo of the technique and show how many things it can block against (if showing a block).

I would dare someone to knock some sense into me.

I certainly wouldn't want to be learning from that "sensei"
