Just to give this another perspective on this.......Do you think that "C" could be the one that is really upset and she is putting the blame for her feelings on her Dad??? When I was that age I found myself on both sides of the situations similar to these you wrote about and would put the "blame" on my Mom. It was not the right thing to do but it was the way I handled it and the way a couple of friends handled it. That could be the reason no one is supposed to talk to the Dad about it. Maybe 'C" was really the one embarrassed about the flood of tears and did not handle it well so she said her Dad said those things.
I also was mad about the way the Dad handled this situation but when you got to the phone situation that is when it hit me that this could be "C" doing this. It IS very possible even though if you asked her directly she would tell you no because she figures that you would never talk to her dad.
The best thing to do is to talk to the Dad. Ask him if he was aware of the crying episode and ask him what happened. It could be that the parents were not even aware of what went on.
Maybe I am TOTALLY wrong on this but you should talk to all parties involved.
