In my class on Wednesday, I passed back some assignments I'd graded, and then I fielded some questions from a student about her grade.

Student: Why did I get marked down right here? (pointing to a clearly wrong answer with the correct answer written beside it in my handwriting with a different color pen)
Me: Umm ... because your answer was wrong.
Student: But that girl got it right. (pointing to no one, as everyone else had gone home by then)
Me: She had this exact answer? (pointing to the answer that she'd written and I'd crossed off)
Student: No. She had this. (pointing the correct answer, written in my handwriting in a different color pen beside her answer, which was was crossed off)
Me: Umm ... I wrote that.
Student: Oh ... Well, then why did I get this one wrong? (pointing to the next question, where I'd again crossed off her answer and written the correct one beside it)

Not everyone should go to college.
