I knew a girl, brought up as a tomboy and exceptionally vigorous, who thought she was as strong as a man; though she was very pretty, though she had painful periods every month, she was completely unconscious of her femininity; she had a boy's toughness, exuberance of life, and initiative; she had a boy's boldness: on the street she would not hesitate to jump into a fistfight if she saw a child or a woman harassed.
