In what way? Parents want their children to have good quality lives; they want their children to be happy. If a man sees a weakness in his son that's bound to keep from having a good quality of life such as running from challenges instead of facing them, and he's heartbroken because until his son learns to find the courage (guts) within himself to be able to face challenges head on, he's not going to have much of a life, how is that revealing of a flaw in the father? The father is going to be heartbroken because he cares so much. If Jock didn't care about Gary so much, it couldn't affect Jock to the point where he'd be heartbroken, could it?
