Try remaining non-verbal. When you try to offer help and they tell you that they know what they're doing, just stop speaking. Don't resist too much or be a bad uke, just don't speak. When they get no help from you, they can't throw it back in your face, right? If your technique is better, it will become readily apparent to all involved (especially in randori
). Don't let them upset you. You are in control of yourself. Take care.
