I just page caught and I am dumbfounded by some of the comments. I think some people expect far too much from very young people. Athletes have to be very competitive and focused in order to be successful; every skater's dream is to win at the Olympics. E.M.'s regularly solid performances probably raised her personal expectations even higher. She heeded Eteri's instructions carefully for years (some which seem to border on the inane), she got injured, she came back before she was totally healed, and then she lost to this newcomer girl who her coach also helped.
She said a sentence or two out of frustration, like anyone would, and then she seems to have moved on. (I find it pretty ridiculous that we're analyzing two teenagers shopping with one another.) When I was 16 and I lost at a competition that I pinned all my hopes on, I was heartbroken and probably said a few less than nice things about other competitors. It's part of life.
For a middle aged coach to betray her student's confidence like that because she is leaving her is petty and pathetic and underlies why skaters are leaving her. There is nothing gained from spilling that information, and E.M. hasn't even spoken publicly about the move. She hasn't said anything unduly negative in return. At best, she didn't take some calls. A reasonable adult is privately bitter, just like E.M. herself was, and then moves on. I wouldn't consider myself an E.M. fan but I don't think she deserves any blame in this situation.
