Dialogue:

Dan: Hi, Jo. What's your dad doing?

Jo: He's installing an alarm system.

Dan: What for?

Jo: Well, there are burglars around here. They're stealing things from people's houses.

Dan: Really?

Jo: Yes, you should tell your parents.

Dan: You're right. They should probably install an alarm, too.

Jo: And you should be careful with your keys. Don't lose them, or leave them near an open window.

Dan: I didn't think of that.

Jo: You know there's a lot of crime in cities these days.

Dan: I think you're right. We should be careful.

Jo: Yeah, better safe than sorry!
