I don't think she even knows that she cheated. The liability that a teacher has by telling a student anything sexual is pretty simple. She would not only be fired but according to the new standards of sexual conduct for teachers she would have charges brought against her. One would think that any person that has enough brains to become a teacher would have enough brains not to get themselves fired.
But then again, she did support biteme. OK, so maybe she isn't that bright.
