On a serious note, this strikingly pretty woman is obviously mentally disturbed. I'd be willing to bet a paycheck on her childhood being one of sexual abuse by an older individual; there had to have been a lot of dysfunctional characteristics...I really feel sorry for her husband, family. Instead of jail, she needs a good psychiatrist to discover her illness and straighten her life. However, ban her from the classroom forever!
On a different serious note, she becomes rather less pretty the more you look at her -- something about her expression is very unpleasant.
