John: Hi, Paul.
Paul: Hi, John.
John: I've got this new project in mind.
Paul: You do? What is it?
John: I'll be straight Paul.
Paul: That's good. Go ahead.
John: Let it be, then, Paul.
Paul: Let it be what?
John: I am thinking about writing a song?
Paul: Really? Have you ever done a thing like that?
John: As a matter of fact I have. Just never advertised it much.
Paul: So what your song is gonna be about.
John: That's the problem, Paul. I was hoping you might suggest something.
Paul: Well, I don't know John. It could be anything really.
John: Like what? Can you be a bit more specific?
Paul: How about world peace. That's important.
John: You really think so? 
Paul: Yes, I do.
John: Sounds a bit boring and unrealistic.
Paul: It is that. But important too.
John is going to write a song. He wrote songs before but did not advertise it. Paul suggested writing a song about world peace.
