I called one of my friends during a "freak out" and she calmed me down. She was right when she said, "there is nothing you can do. You can't change it. It's part of the culture and that's just how it is. Brush it off and relax." While I know she's totally right, I must say that one of the most difficult things about being a teacher is putting all emotions aside, and putting a smile on your face and returning to teach a different class after losing control (because, after all, it wasn't their fault the other situation happened).
On a different note, GO AMERICA!
