How did Professor Joanna ask John to meet her?

M: Excuse me, Professor Joanna. On the paper you handed back yesterday, you said" Please see me". Is there a problem?
W: Well. Have a seat for a minute. Please have a look at the paper, this paragraph here. You analyzed the architecture of the National Cathedral, and you included some information that’s not what you’d call common knowledge. How did you know this?
M: Well. I looked a lot of things up in the art library before writing the paper.
W: John. When you quote something in a paper from a book or others’ paper, you must cite the source. It’s not just a matter of style. It’s a legal requirement. You can do this with a footnote.
M: What should I do about this paper.’?
W: I suggest you do two things. First, go over to the bookstore and get yourself a writing manual. It doesn’t cost very much and the money is well spent. Then once you are familiar with some of the mechanics, I’d like you to rewrite this paper with proper references. In any case, you will need to resubmit it before the end of the term. You’re quite welcome, John. And make sure you get it straight now or it will cause you all kinds of trouble later. Copying someone else’s work could turn into a legal problem.
M: I think I understand now. Thank you very much, Professor.
