“Do not ride your bicycle around the corner”, the mother had told her daughter when she was seven.
“Why not!” protested the girl.
“Because then I cannot see you and you will fall down and cry and I will not hear you.”
“How do you know I’ll fall?” whined the girl.
“It is in a book, The Twenty-Six Malignant Gates, all the bad things that can happen to you outside the protection of this house.”
“I don’t believe you. Let me see the book.”
“It is written in Chinese. You cannot understand it.That is why you must listen to me.”
“What are they, then?” the girl demanded. “Tell me the twenty-six bad things.”
But the mother sat knitting in silence.
“What twenty-six!” shouted the girl.
The mother still did not answer her.
“You can’t tell me because you don’t know!You don’t know anything!” And the girl ran outside, jumped on her bicycle, and in her hurry to get away, she fell before she even reached the corner.

Different ways of talking
Both Joy and Tommy are growing up in the culture of the United States. They are learning what it means to be a girl and a boy in this culture. Their sex at birth, female or male, is now becoming a gender – a way of thinking, speaking, and acting that is considered feminine or masculine. Each culture has its own way of defining gender, and very early in life gender becomes a basic part of a person’s identity.
In the United States and Canada, boys and girls usually play in the same sex groups. Boys play in large groups in which every boy knows his place.
Some are leaders; others are followers. Many boys like to get attention by boasting, or talking how well they can do things.
Girls, on the other hand, usually play in smaller groups. They may be interested in playing fairly and taking turns. For example, when jumping rope, the rope-holders always take their turn jumping.
Dr.Tannen, a professor at Georgetown University, has found that these differences are reflected in the ways that children use language while they play. Boys often use commands when they talk to each other while girls use the form “let’s” when they want to express their preferences, emphasizing the fact that all of them belong to the same group.
These differences seem to be part of growing up in the culture of the United States. If men and women can understand that many of their differences are cultural, not personal, they may be able to improve their relationships and understand that there is more than one way to communicate.
