Have you noticed that our son is kind of weird?

No,I'm too busy recentlly to care for him. What's wrong?

He often comes home very late and talks a lot about computer games with his friends on the phone.

Really? He has got a new hobby?

Yes,but it seems that his hobby is not a good one.

His teacher called today. She said Jim often fell asleep in class these days.

We can't let him indulge in that.

Yes,maybe should i have a talk with him.

Sure. Is he at home now?

No,he won't come back until 11PM.
