A little piece of advice

This is one big lesson I've learned in the past three and a half months: don't give the students any ammunition, because they will shoot you dead before you can blink.

Of course, knowing this and following it are two entirely different things. I woke up late today, and walking into class 20 minutes after it's started is not the best way to maintain authority. Especially since it was my class of rowdies. They all—every single one of them—said "Ooooooh!" in that sarcastic teenage way when I walked in.

So I gave them a pop quiz.

I win.
