Okay, I mean within a particular situation, but what I am trying to ask wouldn't fit within the number of characters alotted for the title. What I mean is, how do you know the difference between those students who may carry around, for the rest of their lives, a mistake they made in one of their first recitals (even as a child) vs. those whom maybe don't care ? And, if you have a student who might let their first recital mistake affect them for the rest of their lives, what do you do about it ? What do you say or not say to them ?
I think that judging the sensitivity of a student in a stressful recital situation is crucial.
