How to Confront a Student for a Problematic Behavior?

In the book, you do come across very humorous and very relaxed. So what does it look like when you are confronting a kid for a real problematic behavior? What does that actually look like? That actually looks like you have to stop this right now. And if you don't, I have to go get an administrator. If that doesn't work, we got to get the police. There are times when a student is being dangerous, that's just point A or point B, man. You can be a very direct person. But my editor was telling some of that down some.
