2am I woke up.

I applied for the position of 8th grade coordinator at my school and I think the interview will be today. Nervous but I found some notes on my Mac that I will print at work to take with me. Usually we're given the set of questions for 10 minutes and have to draft up a response. I would love to get the position but didn't last time I interviewed because I wasn't the successful candidate. I got told I sucked at answering this questions (so I've had more time to think about it):

The bell rings at the end of recess and you have a class that's about to start. As you're leaving the office, reception rings to say there's an angry parent demanding to see you right now. At the same time, a teacher brings in 2 students who have just had a fight at recess. What do you do?
