"No, you can't copy his work."
I said this to a student. She balked. She argued. She complained. But I was adamant. One does not copy another student's work.
"You're just evil," the girl told me.
"Thank you for that lovely compliment," I replied.
The girl stopped copying the assignment. And I was satisfied. I didn't even mind the evil comment. I figured I was due. I tend to use that word a lot myself, so it was probably time that a student would throw it back at me.
