Yes, Play and Learn really covered it well, but the ladies are all right, get a letter out to parents stating the rules and that they must be obeyed without exception. You have to demand respect and I've definitely learned that the hard way so now any time a parent asks for anything special I simply say 'according to our contract.....' and that answers it. My contract is law. My rules cannot be broken and I get angry when they push me or try any tricks so if they want to keep their space they give me the respect I deserve.
