In the brawls that spring up in the yard over the lunch money each kid brings to school, it is the girl who fights with the most savagery, the most viciousness, who wins. The little girls, who have practiced their craft, develop the maneuvers and techniques that make up the essence of this art. They tend to be the ones walking away with a jingling purse while their opponents lie bleeding and unconscious on the asphalt behind them.
