Oh yes, and I did. High school teacher said I didn't have the smarts for college, or any sigmificant accomplishments beyond. I stopped by to visit the school some years later, and made a point of visiting the old girl. Her response: "You did better than any of them", in somewhat amazement. My thoughts at the time: "YES"!!!
Yes I had an instructor like that. I graduated with my degree in spite of her comments and went on to have the career I wanted.
I don't need to go there. She lost her job for what she said to me.
It was made very clear why she was fired. She confronted me for being called on her behavior. She has mental problems. It wasn't easy for her to get another job.
