We're supposed to consider this a classroom environment. They need to be put in perspective. I don't think the 10 minute rule has decreased language in Michigan. I don't produce cards from my pocket like Harry Houdini the first foul word I hear. Girls today are not tha sweet memories of our youth.
Girls love to argue and get value through communication more than boys.
Boys would rather get revenge. I like your tactic. They don't agree with all of them. But I think that they will all agree that the players know the rules when they step on the pitch. Well said, and is what levels the playing field for all.
