Jennie and David are classmate. They are discussing about new rule in their school that students are not allowed to bring mobile phone.
Jennie: I wonder why we are not allowed to bring mobile phone to school?
David: Our teachers think that it has a lot of bad effect to students.
Jennie: Why do you think so?
David: Our friends often misuse it. They use mobile phone to talk during lessons, play game when studying. Sometimes the phone rings when teacher explains something. It's annoyed.
Jennie: Yea, I think so. But, Don't they think about emergency call or students who needs picked up after school time like me. Now, I have to ride a bus. It wastes my time.
David: The bad impact is more than the good one. You know, some our friends save porn movies and watch during school hour. They also send and transfer each other.
Jennie: It's crazy.
David: That's why I agree with the new policy.
