As a suggestion Dan, my father had to teach me, since I was a slow learner, to educate, not castigate. If you educate someone, you make things better for you and them. If you give them shit, you have either hurt their feelings or pissed them off. The first method is more than likely to create a friend or at least good will. The second method; you may create ill will if not an enemy. I wish I could follow his good advice all the time, but I don't. I have to try harder.
