There once was a teacher, who went by the name of Miss Swing. She was a very good teacher, popular with her children, who were all well-behaved and scored very well on all the tests they took. All the parents at parents’ evening either wanted to be her or be with her, and all her colleagues knew she was wonderful in the classroom, the best teacher the school had.
There was one small problem with Miss Swing, though. She would never agree with anyone else.
If you said something was black, she would say it was white. If you told her the weather was cold, she’d reply she thought it unseasonably warm. Anything you said to her, she would contradict if she could. The only exception was when she was on holiday, when she would be as pleasant and polite a person as you could ever meet. Apart from that, she would always disagree with everything you said.
Finally, one day, someone confronted her. “Why is it,” they said, “that when you’re on holiday you’re as charming as anyone, but when you’re in school, or even after work, you can never agree with anyone?”
“Ahh,” said Miss Swing, “I’m just a contradiction in terms.”
