B: "You!"

A: "What are you talking about? What did I do?"

B: "You told Martha that I was on a date? What was that all about?"

A: "No... that's not what I meant. I didn't mean that. She asked me where you were and I jokingly said that you were on a date with Sara. I thought Martha knew that you and Sara were just friends."

B: "She started feeling suspicious after you said that."

A: "I'm sorry man. I didn't know. I didn't mean to screw anything up."

B: "Martha gets jealous easily and it took a while to convince her that Sara was just a friend. Now, I have to explain to Sara that I can't hang around her because of you."

A: "Look. I really didn't mean to, and next time I see Martha, I'll really tell her that you and Sara are really just friends."

B: "Don't bother."
