The above link leads to a discussion with many well known (and not so well known coaches) about the day to day interactions between coaches and students.
There are some interesting stories, particularly about Elaine Zayak, both as a coach herself now, and how she went back to her first coach, whom she left for Burrows when she was very young, to tell that first coach how very, very important she was to Elaine. I do so like Elaine!!
There are also interviews both with Carol Heiss and Lisa Ervin about what went wrong there.
I found it quite interesting.
