Am I the only one to think that whether someone is a good whistler is nothing a psychiatrist would care about? It is just not relevant at all for a psychological profile, is it?
Also, how did Sophie Miller know about the whistling abilities in the first place? A calm guy who "needs no distraction" while sitting in the waiting room surely did not whistle the charts (which would be a form of distraction).
I am pretty sure Bruno Heller wants to set us on the wrong track with this one.
