Remind your sons that the RC or HC just wants to talk and get to know them. I had to tell my son he was not allowed to answer any question in less than 7 words. I also had to tell him it was ok to answer with good success. He kept saying but dad that is bragging. My answer was that if you don't tell them what good things you did, who will? It is tough to get even outgoing young men to talk to adults but again it is a life lesson.
