F: Hello, Bill. Nice to see you again. I heard you went into hospital for a few days. I hope everything is OK. ,M: Yes, fine. I was really nervous just before I had the operation, but strangely enough, the operation was over when I woke up. ,F: It must have really hurt afterward. ,M: Well, the nurse gave me plenty of pain killers, but it did feel uncomfortable. I wasn't permitted to eat anything for 48 hours. That was the worst thing.
(A) F: Yeah, you must have felt very hungry after 48 hours' hunger. (B) F: Just a minute! I do not quite follow what you are saying, would you mind repeating that? (C) F: Yeah, eating only porridge for 48 hours must have made you go crazy. (D) F: That was really tough for that you just could drink water for 72 hours.
