Going on duty as a community leader

On some of the days at school, I go on duty. What I have to do is sort out arguments, stop people from driving on the scooter or bike through the pathway in front of the playground. I need to teach the little kids that riding thought the pathway in front of the playground is bad, and they need to walk their bike or scooter. Sometimes we need to keep them from going on the grass when it is too muddy. Once, there was a kid that drove through the pathway really fast. We went to go stop him and he rode his bike away. When he could not ride the bike away he ran away. When 5 of us managed to stop him, he would not listen to us and would try and run away. We then had to get a teacher to get him to listen to us. Overall, I think that there are some people who listen and some who don't want to and some who just don't.
