[speaker001:] Professor, I will not be here for our next class meeting.
[speaker002:] Is this absolutely necessary?
[speaker001:] I tried to work something out, but I really do have to miss one class.
[speaker002:] Will you be able to make up the work you missed?
[speaker001:] I'm going to be doing a lot of extra reading.
[speaker002:] Remember that I will only let you miss one class meeting per semester.
[speaker001:] Yes, I remember.
[speaker002:] Could you e-mail me this week as a reminder?
[speaker001:] Sure, no problem.
[speaker002:] Make good use of that day off; you'll only have one this semester!
