I agree that Gracie might not have phrased it right, but I still think it's a packaging problem. Gracie is 18, young in the grand scheme of life but not that young in ladies' figure skating. She is who she is, and at this point I'd love to see her make the best of what that is and not try to be something she isn't.
But I don't see how trying mime is being something you're not, though. We assume that it's easy for Gracie just to say "hey I'm a power skater, I'm going to express myself that way now," but as golden411 said, she is having trouble expressing anything.
Expression of one's self doesn't come naturally. I think mime is not just about the "act' but also the ability to look at oneself. I hope Gracie gets something good out of it.
