I am sorry her last teaching days were not happy. She deserved more than that. But ... as you said, Helen, the parents and students did come to have all the power ... and (a) her reputation would have preceded her and (b) she would continue her relentless putdowns which would pay off only at final exam time ... I can see the "power" not putting up with her teaching style. Too bad, isn't it. There was much to be gleaned from her knowledge.
