When her five daughters were young, Helene An always told them that there was strength in unity (团结). To show this, she held up one chopstick, representing oneperson. Then she easily broke it into two pieces. Next, she tied several chopsticks together, representing a family. She showed the girls it was hard to break the tied chopsticks. This lesson about family unity stayed with the daughters as they grew up.

Helene An and her family own a large restaurant business in California. However, when Helene and her husband Danny left their home in Vietnam in 1975, they didn't have much money. They moved their family to San Francisco. There they joined Danny's mother, Diana, who owned a small Italian sandwich shop. Soon afterwards, Helene and Diana changed the sandwich shop into a small Vietnamese restaurant. The five daughters helped in the restaurant when they were young. However, Helene did not want her daughters to always work in the family business because she thought it was too hard.

        Eventually the girls all graduated from college and went away to work for themselves, but one by one, the daughters returned to work in the family business. They opened new restaurants in San Francisco and Los Angeles. Even though family members sometimes disagreed with each other, they worked together to make the business successful. Daughter Elisabeth explains, "Our mother taught us that to succeed we must have unity, and to have unity we must have peace. Without the strength of the family, there is no business."

        Their expanding business became a large corporation in 1996, with three generations of Ans working together. Now the Ans' corporation makes more than $20 million each year. Although they began with a small restaurant, they had big dreams, and they worked together. Now they are a big success.

    To understand how Americans think about things, it is necessary to understand "the point". Americans mention it often: "Let's get right to the point." They will say, "My point is…" "What's the point of all this?"

    The "point" is the idea or piece of information that Americans suppose is, or should be, at the center of people's thinking, writings, and spoken comments. Speakers and writers are supposed to "make their points clear", meaning that they are supposed to say or write clearly the idea or piece of information they wish to express.

    People from many other cultures have different ideas about the point. Africans traditionally tell stories that express the thoughts they have in mind, rather than stating the point clearly. Japanese traditionally speak indirectly, leaving the listener to figure out what the point is. Thus, while an American might say to a friend, "I don't think that coat goes very well with the rest of your outfit," a Japanese might say, "Maybe another coat would look even better than the one you have on." Americans value a person who "gets right to the point". Japanese are likely to consider such a person insensitive if not rude.

    The Chinese and Japanese languages are characterized by vagueness and ambiguity. The precision and directness Americans associate with "the point" cannot be achieved, at least not with any grace, in Chinese and Japanese. Speakers of those languages thus have to learn a new way of reasoning and expressing their ideas if they are going to communicate satisfactorily with Americans.

    When Lina was awoken by the sound of thunder, she was alone on the island. The air was cool and bullfrogs croaked. It was that brief moment when the summer sun had set but the stars hadn't yet appeared. Lina rubbed her eyes and looked around.

    "Hello?" she called. "Celia? Marie?"

    There was no response.

    The moon was rising now, shedding light on the island. They had always called it "Forgotten Island" because no one but they seemed to remember its existence. It wasn't on any of the maps they could find, and even the forest rangers didn't know about it. Lina loved that the island, hidden in a heavily-wooded side stream of the river, was a secret between the three friends -her, Celia, and Marie.

    But now Lina was here alone, and it was night. Worse still, it was her own fault.

    "Come on, Lina, let Marie row the boat." Celia had said. Marie was two years older than Lina, but she was a hopeless rower. That's why Lina refused and rowed the boat to the island. The argument that followed the refusal took the usual form. Celia took Marie's side, as she always did. Lina had exploded and yelled at them to just leave. So they got back in the boat and left.

    A bolt of lightning crossed the darkened sky, accompanied by a deafening thunder clap. The storm was here. As the first cold raindrop slid down her neck, Lina's mind returned to her current problem. She was stuck here by herself. She just hoped she didn't become as forgotten as the island. The thought of it sent a chill（寒意）down her back.

    Suddenly, Lina spotted something in the water. It was a boat, and inside it were Marie, Celia, and Marie's dad, who was steering through the fast flowing waters. As the boat approached, they saw Lina waving and the worried expressions on their faces turned to relief.

    In her excitement Lina jumped into the river. Only once she was in the icy water did she remember how fast the water was moving. Luckily a strong arm reached into the water and pulled her out. She smiled weakly at Marie's dad and, without a word, hugged Celia and Marie. They didn't seem to mind becoming wet.

    For years, decades in fact, I've puzzled over the response most people have when I tell them I mostly travel alone.

    "You're so brave!"

    Why is it that a woman travelling alone, as I have often done for months at a time, is perceived to be "brave", whereas men who travel alone are entirely unremarkable?

You are only brave when you are afraid of something but still do it anyway. I have never been afraid of travelling alone.

    The first time I travelled alone was when I was 19. I was due to travel in Europe with a friend at the end of the summer. She announced by letter two days before our departure that she would be leaving me halfway at Vienna. It was too late by then to rope in another friend, so it was either to go home after Vienna, or keep going by myself. I kept going. I got on trains by myself, checked into hostels by myself and found my way around by myself. It was weird at first, but later I stopped worrying about it.

    When I got back to Ireland after that trip, I felt proud of myself. I had done something I had assumed would be hard, and it had turned out to be not hard at all.

    That was three decades ago, and since then I have travelled all over the world, usually on my own. I still do what I did then, which is to keep a diary. The greatest gift of solo travel has been those I've met along the way. I may have set off alone each time but I've encountered many people who became important to me. I met my husband in Kathmandu, Nepal. I met lifelong friends in Australia, Poland, Hungary, Turkey, India, Indonesia and many other places.

    Reading can be a social activity. Think of the people who belong to book groups. They choose books to read and then meet to discuss them. Now, the website Book Crossing.com turns the page on the traditional idea of a book group.

    Members go on the site and register the books they own and would like to share. Book Crossing provides an identification number to stick inside the book. Then the person leaves it in a public lace hoping that the book will have an adventure, traveling far and wide with each new reader who finds it.

    Bruce Pederson, the managing director of BookCrossing, says, "The two things that change your life are the people you meet and books you read. BookCrossing combines both."

    Members leave books on park benches and buses, in train stations and coffee shops. Whoever finds their book will go to the site and record where they found it.

    People who find a book can also leave a journal entry describing what they thought of it. E-mails are then sent to the BookCrossing to keep them updated about where their books have been found. Bruce peterson says the idea is for people not to be selfish by keeping a book to gather dust on a shelf at home.

    BookCrossing is part of a trend among people who want to get back to the "real" and not the virtual(虚拟). The site now has more than one million members in more than one hundred thirty-five countries.
