A: Hi, Kate! Come in! Tell me about the talk! Was it interesting?
B: Yes, I learned a lot. For example, are those your keys there?
A: Yes. Why?
B: Well, you should never leave keys near doors or windows, especially if they are open.
A: Why not?
B: Well, someone may come in and take your keys. And they know where you live, too!
A: You're right! What else did you learn?
B: Well, you should always sleep with your mobile phone beside the bed. And you should keep it switched on.
A: I see! That way, you can contact the police immediately.
B: Yes. And if you have a garden, you should have dusk-to-dawn outside lights.
A: That's a good idea.
B: And these should be two and a half metres high, at least.
A: And was there anything else?
B: Yes. If a stranger knocks on your door, always ask them for ID.
A: But what should you do if you're not sure?
B: You shouldn't let them in!
