So, I had to write a second Hump Day Hmm. This story just shot out of my memory when I read another poster's comments.
In graduate school, I had a definite experience of using my words that cost me. I was taking a human resources class, and the profressor was terrible. She seemed to have little experience in what she was teaching, and she never talked at great length on the final project - creating a benefits package for employees at a business based on a given cost maximum and certain needs as a minimum. My teammates were an Indian (no US HR experience), a Navy officer (again, no HR experience), and me (who'd never had a benefits package with a job before). We did our best and, at a minimum, we complied with the project guidelines. But I wrote an anonymous (supposedly) evaluation of how terrible the professor was. We got a 40 on our project, and I got a C for the class. We appealed the grade, but since the professor was the Dean of Research, we knew after the first level the grade was not changing. I only found out later, from a classmate who worked in the office that processed evaluations, that many times professors came in to review the hand-written evaluation (despite assurances they were anonymous) to recognize the handwriting. I am solidly convinced I got a C because I ripped my professor to shreds in that evaluation.
My recourse, though, was simple. Any solicitations from my school for funds came with one question back, "Does Dr. [her name] still have a position there? Call me when she's retired."
She retired early this year, so I can now give to the school I love so much again.
