Dam!

J: Damn!
Me: Joseph! We do not say words like that.
J: I was saying the kind of dam that blocks water.
Me: Ummhm. Just because you hear other people say those words doesn’t mean you can say them.
J: Daddy says damn it.
Me: I know. He has a bad habit. But I want only clean words to come out of your mouth. Not dirty words.
J: Or dusty words.
Me: Um. Exactly.
