I find it impossible to predict which bonmots my students will be impressed by. I say snide offhanded things all the time, but once or twice a year I will say something that will get such a large reaction that the entire class will be thrown into an uproar as they all tell the kid I was talking to that I sure got him that time. But I can't see a difference between one remark and the other --- at least, why one remark should be so clearly superior in their minds.
Here's today's example.
Boy, 17, knocks the ice-tea bottle of girl, 15, off her purse and onto the floor. I tell him to pick it up.
Boy: She called me a bitch!
Me. And then you proved her right.
I mean really. That's all it takes?
