TracyN -
I'm sorry you have had some difficult experiences with this instructor, but I generally, especially lately, try to look on the bright side of things and I am grateful that:
(1) You were never hurt. I can think of a few situations you have been in with her that could have easily ended much worse than they did. I'm glad they didn't.
(2) It's all added up to a situation that has essentially resulted in her being run outta town... And less of her around town is probably a good thing. Less potential for hurting more people, or hurting them more seriously.
(3) It's caused you to sever ties with her. So thankful for that... Safe diving not only has to do with your own judgement, training, and self sufficiency, but also has a lot to do with the team you're a part of. I'm glad she's not on yours anymore.
(4) Maybe it's made you less trusting - also a good thing I think. As much as I like you as a person and have SO enjoyed seeing your passion for diving, I have always been wary of your judgement. A lot of it has to do with something that happened in the water long ago, a few decisions you made affected my team in a negative way and it pissed me off. I know that since then you have become a drastically different diver, but a lot of the stories I've heard, the two worst of which involved Ms. Treanor, made me question whether, though your diving had most definitely improved, your judgement had. If you take away anything from this situation, being careful who you trust is not a bad lesson.
I hope your actions are not too much out of spite and instead come from an honest respect for the sport and the dangers of poor training, especially at your level. I know you dive a lot, and you have been trained by some very good people (and some bad) both formally and informally, I hope you find you can use that training to make sound judgements about your own diving, and then trust your own judgement more than the guidance of others who may not be as trustworthy.
I hope that didn't come off preachy - I bet you have gotten tired of being preached at and I really am not trying to do that. I mean it sincerely as a friend - I really hope you are a safer diver for all this. I don't want to see you die, and I'm glad you cut ties with her because I was afraid that if you continued diving the way you did with her you might end up dead one day.
