The discussion was only about the parent sharing with the professionals her experience with her son who is deaf-blind, and then later the parent asking a question to the professionals about an issue regarding her son. It was not about all the other aspects that you mention in your comment. It was successful because it was an open, respectful and honest exchange and everybody contributed and learned from the experience.
