A Fickle Exchange

Kevin: You're a very fickle person.
Mike: No I'm not!
Kevin: Sure you are, you're always talking one way about one thing at one time, and then a week later you're the other way on that same thing.
Mike: Oh. I kind of think being fickle isn't necessarily a bad thing.
Kevin: I didn't say that it was, just that you are.
Mike: Yeah, I am fickle.
Kevin: That didn't take a week.
