Júlia: Hey, girls! Hang on a minute.
Anna: Oh, no. I think we're in trouble.
Júlia: I saw you leave the computers on.
Sara: Oh, I'm relly sorry. We forgot to turn ghem off.
Júlia: Well, can you remember next time, please?
Anna: Yes, of course.
Anna: Ok, we didn't mean to cause a problem. We'll go and turn them off now.
