A: Hi, this is Betty.
B: Hi, Betty. It's Larry. I need to know how many smoke detectors are in your apartment.
A: There was one when I moved in. Then I added one.
B: Do both detectors have fresh batteries?
A: I always keep them fresh. I don't want to burn to death.
B: That's good. I have to come by there and check out all of the detectors.
A: Not a problem. When will you be here?
B: I'll be letting myself into all the apartments on Thursday at noon.
A: If it's raining, make sure you wipe your feet before you come inside, okay?
B: Not to worry. I'll be in and out of your place in a flash.
