Student: Miss, what would happen if I punched you?
Me (thoughtful): Well, did you knock me out?
Student (taken aback): Um, yeah.
Me: Then I’d be passed out for awhile and I hope that someone else would call the office or security.
Student (nodding): … but what if I didn’t knock you out?
Me: Hmmm, are you only punching me?
Student (considering): Yes.
Me: Well, I’d try to get away and make sure you don’t punch anyone else. Then I would either hit the emergency button or go next door to contact security.
Student (nodding again): But what if you can’t do that?
Me (with a smile): Sweetie, I’m not going to punch you back.
Student (disappointed): Oh.
