Did you speak to your dad about going camping?

Yes, I did.

What did he say?

He said it wasn't a good idea.

Why?

He thought it would be too cold.

Oh.

Yes, and he said that it was going to rain.

Really? I haven't heard that.

Yes. He said he read the weather forecast. He also said that we have to revise our exams.

Yes. I suppose he's right. We have got an exam on Monday.
