M: Helen, I want to have a word with you. ,F: Is it about the appointment yesterday evening? Forget it. It doesn't really matter. ,M: But I must say sorry to you. I didn't mean to break my word. I was about to leave home when my mother suddenly passed out. I took her to the hospital and looked after her all night. It was not until this morning that I remembered my date with you. ,F: Oh, I'm sorry to hear that. Is she OK now? ,M: She's alright, but I'm terribly sorry to have kept you waiting last night. ,F: I quite understand it's not your fault, but don't forget to call me up next time if you can't come.

(C) M: Thanks for your understanding that I couldn't visit you in the hospital because of work yesterday. (D) M: Don't thank me. We are friends so I should take care of you when you are sick like yesterday.
