answer: #Person1# wants to ask for leave from Professor Li's class and May will bring the note to Professor Li. They both think Li doesn't teach well but May thinks #Person1# is impolite to be absent. #Person1# explains that #Person1# is busy with #Person1#'s work in the Students' Government.
documents: #Person1#: May, could you bring this note to Professor Li for me today?
  #Person2#: Sure, no problem. Asking for leave again? You have been absent from class five times this semester.
  #Person1#: I know. But attending Miss Li's class is just waste of time. No more than one third of her students will go to her class.
  #Person2#: I agree that Miss Li doesn't teach so well. Most students either sleep or do other things in her class.
  #Person1#: Yeah, my boyfriend plays the video game every time in class with me. Or I chat with my friends through text messages.
  #Person2#: Fortunately her class is just an elective course, not as important as compulsory courses.
  #Person1#: Right, so we must spare some time to attend selective courses.
  #Person2#: But isn't it too impolite to be absent?
  #Person1#: What can I do? I have things to do in Students'Government.
  #Person2#: Oh, I thought you just gave an excuse on this note.
  #Person1#: Sometimes I will try various excuses. But this is my last time asking for leave. Or I will have a bad record.
  #Person2#: Yeah, besides, your credit will be deducted. That is kind of serious.
  #Person1#: I have been absented from many classes this semester just because of my work in the Students'Government.
  #Person2#: You can't write with one hand and draw with the other.
  #Person1#: I am thinking about quitting my job in the student government. But before that, I must do my job. Bye. Don't forget about that note.
  #Person2#: You can count on me.
