Jon: I'm going to be out of town for a few days.
Devin: Where are you going?
Jon: On a business trip to New York. Can you keep an eye on my house?
Devin: Sure. There have been a lot of burglaries these days.
Jon: I know. I'm a little nervous to leave.
Devin: Do you have an alarm system?
Jon: No. Do you have one?
Devin: Yes. I feel safer with it.
Jon: Maybe I should get one too.
Devin: That's a good idea.
