I had her about ten years ago. She was one of the best teachers I have ever had. She was tough, but she was very clever in dealing with her students.
She wasn't degrading, she was witty. She never said one thing that wasn't true, and I only hope I have half of her talent for verbal irony. Did you want her to hold your hand?
I had this teacher years ago and I still remember what a terrible person she was. She is mean-spirited and degrades students.
