Or "He's on medication"... what it really means is that he's an a**h**e, but we don't want to admit it.
I always disgustedly roll my eyes when someone tried to play down someone's destructive/abrasive behavior by saying, "He needs more training", when I know very well that the person in question is simply a no-good jerk, and so no amount of "training" or "counselling" in gonna help him... if he's evil or selfish by nature, there's nothing that others can do to "reform" him; he himself has to WANT to change his ways before any positive progress can be made.
