Curious

I received an unexpected email from a student today, a student with whom I spent 45 minutes in conference on Wednesday talking about the research question for our course's final research essay. I was actually looking forward to what the rough draft would be like for today's class workshop, but the student was absent. Now I know why:

email in total:
I wanted to inform you that I am dropping your class. I have felt that ever since you told me that it is undetermined as to whether or not I will pass this semester, it seems pointless to take that risk and have it affect my GPA. I have spoken with a number of students about what has happened throughout the semester and have found out that I am not alone. I am very disappointed with my decision, but I feel that I am left no other options; which you proved to me more thoroughly on Wednesday with our meeting when you said that you can’t guarantee that my paper will be successful because you don’t understand my viewpoint - I left your office feeling very disappointed and very frustrated. Since then, I have had time to think about my decision over the weekend and still did not know up until a few minutes ago, but I plan to meet with a counselor this week to discuss what has happened and I will let you know if there is further information that I need in order to drop.

I suppose it's good news that the student is talking with a counselor. Perhaps it's required since it turns out that my office mate has had this student in class three times before, and the student has already dropped FYC twice: my class was the third attempt at taking the course. Perhaps the student is on probation or something.

I'm especially curious about the "guarantee" language: I wonder how many other instructors ever guarantee that a student "will be successful." I wonder if there's a "money-back" clause now in applications.
