A: Hello, Betty speaking. B: Hey, Betty. This is Larry. Tell me how many smoke detectors you have, please. A: This apartment came with one, and I installed another one. B: Are there fresh batteries in each of them? A: Each detector beeps when the battery is low. They're not beeping. B: Good. I'm calling all the tenants because I have to check all the detectors. A: Okay, What day were you thinking about dropping by? B: I'll be at your building at noon on Thursday. If you're not there, I'll let myself in. A: If you're thirsty, you can grab a beer or soda out of my frig. B: Thanks, but it'll only take me about two minutes to test them and leave.
