Why can’t we write it off to her having a bad day and that the pressure finally got to her. For all her skill, professionalism, talent, and support, she is still a fairly young woman. And I don’t say this to be sexist or condescending. I am the father of two successful, wonderful daughters, aged 28 and 31; at 22 they were still in the process of discovering who they were.
I would like to have a "bad day" and be 4th in the world at anything.
