W: Before you sign the lease, do you have any questions?
M: Yes. Are we allowed to sublet the apartment?
W: No. I’m afraid subletting the apartment isn’t permitted.
M: I see. Well, is it all right to use the fireplace?
W: No. You mustn’t use the fireplace under any circumstances.
M: Oh. Well, do you allow people to have pets?
W: No. That’s out of the question. We don’t permit anyone to have pets.
M: How about parking in front of the building?
W: I’m sorry. You are not supposed to park in front of the building.
M: Oh.
W: And before I forget, I should mention that you may not alter the apartment in any way without permission. Now, do you have any other questions?
M: No, I guess not. I think you have answered them all.
