Gender norms are a controlling force in our society. We see that boys act one way and girls act another way. When boys grow up they play with cars, sports, violence. Boys grow up horsing around fighting with each to shows who is stronger and tougher. When girls grow up they play with dolls, braid each others hair, play house.  The girls act all lady like. The roles of genders are a big controlling force that shows the structure of each gender.
