now that I have read what you did in your other post, I do not see anything inappropriate in what you said in class. I think it was a valid contribution. I am an a student and it is one I would have thought of myself based on the discussion you describe. you did nothing wrong. do not put yourself down because you have a teacher who doesn't allow freedom of expression. you guys veered off her lesson plan and she didn't know how to bring it back on track is probably what happened. have confidence in yourself and take care.
