My marketing teacher was such a goof most of the time but he'd get upset for the same reasons. It boils down to: Freshman are immature goof offs, and sophmores kinda are too. Obviously you get some nice ones, but high school students period are crappy to deal with. Haha, I speak from experience, as I am one. XD

Journalism isn't always on everyone's list of most favorite either. High sschool especially, we're young, we can do the work later, we have better things to do. We don't mean it in a way that's meant to hurt you, or make you feel inferior, it's just how we are. We're still young, we can be inmature. If the kids tried hun, they'd get through the class. It's not your fault.

I'd talk about maybe alternating teaching classes or something with your boss though, and why not become a professor on it? At least college students (generally) are there cos they want to and will be mature. Don't hold yourself back!

Hope you feel better soon! *hug*
