{{Scrappy}} What they said. It sucks that she has put you in this position, but she is still so very lucky to have such a wise and loving aunt.
Hell no. I can't imagine them being that damned naive.
I know 2 Olympic athletes and they are not even remotely naive. They are fanatical about knowing every single thing that goes into their bodies because they can't risk blowing all their hard work. In theory I can see some trainer giving an athlete some banned substance without their knowledge, but they sure as hell should know better.
