Feedback. It's better to give than to take. Protecting your ego from those vile and insipid assaults you should respond (showing your loveliest smile): "Thank you for pointing out this flaw in my performance, I admire your unsellfish consideration of my emotional vulnerability. Oh boy, I still have so much to learn (sigh deeply and look at the ceiling), will it never end? ". (Legend has it that real pro's can actually fill their eyes with tears, not blinking for maximum effect)
