[speaker001:] Are you free on Friday evening because we were wondering if you would like to come round for dinner?
[speaker002:] Oh, thank you very much. I 'd like to come, but I 'm afraid I 'm busy that evening.
[speaker001:] That 's a pity! Then when would it be a good time for you?
[speaker002:] Well, I 'm not too sure, actually. I 'Ve got a lot going on the next couple of weeks. Why don 't I call you later?
[speaker001:] Okay, that 's fine.
