don't worry. maybe it's a chance to express that unrequited love - and sometimes disturbed feelings when they tell you you didn't play well. sort of a love/hate thing. maybe this is good for us because we fear sticking out our tongues and waving our hands when they turn around - yet, who knows, they may be doing that to us when we walk out the door. despite the imperfections he finds in my playing (which is good to know), i would still kiss my piano teachers feet after he plays a recital. he always proves what's possible and it's nice to have someone show you and not just tell you. the most beautiful music comes from his studio door when he's practicing.
