Gender stereotypes Being a father of three children I'm now absolutely sure that there is no so called gender-determined character. My elder kids - a son and a daughter are both the illustration for the famous book by Otto Weininger "Sex and Character". The boy is a choleric, who is crazy about cars, military machines etc, while a girl is flegmatic, likes cooking and can recognize all of your emotion even you try to hide them. But the youngest daughter breaks all stereotypes: she is very active (not to say agressive) in a kindergarden, likes risk and speed, plays with toy-cars, and even starts looking to my car.
