You ever see "mean girls"? Well, SOME females have this stupid idea that males will only like them if they are dumber than the males. The protagonist in "mean girls", who is GREAT at math, really likes a guy and acts like she is an IDIOT in math. In the movie, you hear what she is thinking as the poor boy, who is bad at math, tries to explain to her, INCORRECTLY, how to do a math problem. I have had similar experiences in life.
HEY, some jerks are paid ONLY to try to "help" some people. It is sometimes their highest aspiration.
