Arthur: Do you like to play computer games, Thomas?

Thomas: Not so much.

Arthur: I like them very much.

Thomas: Why? I think it's children's habit to play them.

Arthur: You're wrong. Everyone can enjoy a lot from playing computer games.

Thomas: But I still think it's a waste of time and it does harm to our eyes.

Arthur: It won't if we can control ourselves and play them at suitable time.

Thomas: Sounds funny, but I think it's difficult to control yourself. You should work hard at your courses.

Arthur: Ok, I will.
