That's a great question...that rule does sound self serving I know.
I like to think about it this way...it's my job to make sure that kids are doing the right thing in the classroom, for their safety. We could have 8-10 rules about all of these different things, but that gets to be too much of a management problem. Rule 5 is a catch all rule that helps kids understand that they need to be doing the right thing. The rule we really want them to follow, understand, and make their own of course is Rule 4; Make Smart Choices...Rule 5 says the same thing, just in a fun way.
There are still going to be skeptics for the reasons you mentioned just like there are with everything in our lives. The important thing is that we are trying to change relationships with students, teachers, and administrators. I would keep doing what you are doing and the people around you will see the great results and come begging for you to talk with them.
Keep us posted on your adventure of WBT!
