For an acting teacher, it is essential to accept student's personal truth when criticizing their work. When I taught a master class in Crete (Greece), I had students from various countries, but the majority was from Greece. Since my best friend is Greek, I knew their temperament, and their gestures are very different from mine. There I had a student that I could not believe when she did a short scene. I told her, "I don't believe you because of the way you move your arms." Either she doesn't move them enough or she moves them too much. She admitted, in her real life, she uses hands much more when she acts. I told her to repeat the scene and use her hands as she would in her everyday life. The scene came to life.
