Two boys and a girl are walking down the hall. Let's call them B1, B2, and the girlfriend. The two boys are pushing and shoving each other in the hall. It's not a fight, it's just dumb sophomores pushing each other.
Me: Hey, you guys, knock it off. Keep your hands to yourself.
B1: We weren't doing anything.
Me: Just stop the goofing off in the hallway, please.
B2 grabs the girlfriend by the hand and the three continue to walk down the hall.
B1: Hey, Mrs Binggeli, aren't you going to tell them to knock it off. Look! They didn't keep their hands to themselves. Isn't that a public display of infection!
I ignore their "infections" and continue to walk down the hall.
