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.
(A) F: Relax, you should have felt nervous about your illness, it must be cured after the operation. (B) F: I’m sorry, I didn’t catch that. Would you mind speaking more slowly? (C) F: I really felt nervous about my sleep too, because like you, I could fall in asleep for many days. (D) F: I'm very sorry to hear that the operation you felt nervous failed at last.
