I actually am a licensed substitute teacher. And I've served plenty of time in Indiana schools.

Yeah, they do tend to get a wee bit rowdy, but I saw no violence or such in the classes I've been in. There has been the usual silliness like paper airplanes and such, but nothing that would get anybody hurt.

I've also learned that they are respectful if you respect them. Tit for tat, with the benefit of the doubt.
