Peter: You stole my project idea.
Kevin: I did not. That was my idea.
Peter: I came up with that idea during our meeting yesterday.
Kevin: I don't remember that.
Peter: You are a liar! You said it was a great idea.
Kevin: It's too late. I already presented the idea to the manager.
Peter: I am going to tell her that you stole my idea.
Kevin: You don't have any proof.
Peter: Yes, I do. I recorded our meeting.
Kevin: You are very sneaky.
