M: Professor Day. May I see you for a minute?
W: Sure. Come on in. What’s the matter?
M: I’ ve got a problem. I need your technical writing class, so I went early to the registration area, but by the time I got to the front of the line, it was closed. See, my advisor signed my course request and everything.
W: That’ s a big class already. If it is closed, that means I have 50 students in it now.
M: I’ m not surprised. It’ s a really good class and many students want to attend it.
W: Can’ t you take it next year? We offer it every fall.
M: Well, that’ s the problem. I’ m supposed to be graduating this spring. But, of course, I can’ t graduate without your class.
W: I see. In that case, I’ ll sign for you. It looks like there will be 51. Take this form back to the registration area. They will get you in.
M: Thanks, Professor Day. I really appreciate this!
