Nine hours later, I became the proud father of a handsome nine pound baby boy. So, if I'm slow to answer your e-mails, etc., now you know why. If you see someone doing something wrong, tell them what you expect of them, clearly and emphatically. If the wrong behavior persists, express expectations again and again. It may ultimately be necessary to give the person a choice of either stopping the behavior or leaving the group.
Positive reinforcement is the absolute key to guiding our children.
I believe you will find that one honest and sincere praise is worth a hundred reprimands. Thanks Avi, for IdeaNet. You are performing a great service for all of us. Speak to the person in question privately, too. Be firm but fair about rules which should in any case be spelled out at the beginning of camp or retreat - if you didn't explain these expectations or make them sound fair, you set the system up like an obstacle course.
