APOLOGIZE AND EXPLAIN

Berta: Claudia! What's going on?

Claudia: What's the matter? What have I done?
Berta: Look at my computer. Have you broken it?
Claudia: Sorry, Berta. I didn't mean to. I didn't realize that it was new.
Berta: Claudia, you know I don't like it when you use my computer.
Claudia: Well, it hasn't happened before.
Berta: Claudia! It's the second time that you've broken my computer!
Claudia: OK. Listen, I'm really sorry. Don't worry. It won't happen again, I promise.
Berta: I hope you're right. We'll see.
