Paul: Why do you ask so many questions about the girl living with your brother?
Jane: He has not answered my emails for many weeks.
I think I know the reason why.
Paul: Why?
Maybe he is just busy.
He is probably too busy to write to you.
Jane: I think it is because he is in love with this girl.
Paul: Why do you say that?
How do you know?
Jane: Why do I say that?
Paul: Yes, why do you say that?
Jane: We used to write each other all the time.
We sent emails to each other every week.
He stopped writing me.
Paul: So what?
He probably has other things to do.
Jane: Now I never hear from him.
He no longer writes to me.
