answer: #Person1# and #Person2# are talking about the security of the White House and going to visit it. #Person1# jokes that a gun can't be taken into it and #Person2# warns that it is improper to make such a joke.
documents: #Person1#: But it's the White House. The president and his family live there. They won't let us see most of it. Probably we can only see a couple of rooms.
  #Person2#: No, that's not true. The White House is very big. And there are a lot of historical exhibits there. The tour will take us through many different rooms. I read about it in the guide.
  #Person1#: Hmm. If that's true, then the security there must be very good. Because it's strange to think they will let people walk around in the White House.
  #Person2#: I'm sure the security is very tight. Probably they will make us walk through metal detectors like at the airport.
  #Person1#: So I can't take my gun then.
  #Person2#: Don't always joke like that! You don't have a gun.
  #Person1#: Yes, it's true I don't.
  #Person2#: You shouldn't say things like that. You could get arrested!
  #Person1#: What? Do you think someone will arrest me for making a joke? Someone will arrest me here at the breakfast table?
  #Person2#: No. But if you say something like that in the White House, they may take it seriously. Sometimes I think you joke too much.
  #Person1#: I'll be careful. Don't worry. I don't want to get arrested by the FBI. But how long does the White House tour last?
  #Person2#: I'm not sure. I think it lasts about one hour.
  #Person1#: Alright. We should take a taxi over there right after breakfast.
  #Person2#: First I want to look in the travel guide. Maybe they don't have tours in the morning.
  #Person1#: That's a good idea. Do you want some more coffee?
  #Person2#: No, I'm fine.
