Decision-thinking is not unlike poker—it often matters not only what you think, but also what others think you think and what you think they think you think. The mental process is similar. Naturally, this card game has often been of considerable interest to people who are, by any standards, good thinkers.

    The great mathematician John von Neumann was one of the founders of game theory. In particular , he showed that all games fall into two classes : there are what he called games of “ perfect information ”,games like chess where the players can't hide anything or play tricks : they don't win by chance , but by means of logic and skills . Then there are games of “imperfect information”, like poker, in which it is impossible to know in advance that one course of action is better than another.

    One mistaken idea about business is that it can be treated as a game of “perfect information”. Quite the reverse, business, polities, life itself are games which we must normally play with very imperfect information. Business decisions are often made with many unknown and unknowable factors, which would even puzzle the best poker players. But few business people find it comfortable to admit that they are taking a chance, and many still prefer to believe that they are playing chess, not poker.

    I was born in Thailand, where I feel at home. I am used to jumping on to a song taow (red taxi), and squeezing (挤过) in between two strangers. I am used to bargaining at the market to get a shirt that I like. I love telling bilingual (双语的) jokes and I am used to the surprised looks I get from the Thais when I can speak their language fluently.

    Every two years my family goes to America for the summer, and every two years my world is turned upside down. The prices of everything are three times what they were in Thailand, but there is the sweet drink Dr. Pepper! And Bluebell Ice-cream! And everything you could imagine! I am amazed at it all, but the biggest change for me is the people. There are white people everywhere. I am not tall but average (中等的), my yellow hair is no longer out of place, and speaking English no longer draws looks. I should feel comfortable. I'm not out of place anymore, and nobody is looking at me, but I feel like they are. Now I feel out of place and different. I'm not used to giving people handshakes and hugs when I meet them for the first time. I get looks when I have trouble figuring out how much money to pay. I know different music, different places, and different fashion. I can't understand these people who have never left their town or city.

    Still, there are quite a few perks about living overseas. I get to meet people from all over the world, and I know how to adjust to (适应) different cultures and places. I have been to places most people see only in geography books. Still, being so different makes it hard to know who you are. I'm not Thai, but I am not American either. I am a mix of both cultures, a third culture kid.

    The best festivals in Europe

    Whether they're in the countryside or a post-industrial landscape, Europe's yearly festival calendar means new events, old favourites, crazy people and great charm.

    OFF Festival, Poland

    A small festival in Katowice in south-west Poland, OFF has, over the past 10 years, built an international audience thanks to a challenging and interesting mix of acts. This year's selection focuses on female artists: singer-songwriters Feist and PJ Harvey headline, while Swedish pop singer Anna von Hausswolff and classical composer turned electronic producer Anna Meredith are also on the bill. Meanwhile, the experimental poetry and performance project by Moor Mother will undoubtedly be an unmissable show.

    Melt, Germany

    What would Melt be without its “sleepless stage”--a non-stop music marathon that runs from Saturday morning to midday on Monday? The German festival for those who love an all-hours party takes place in Ferropolis, Gra fenhainichen. This year, the festival celebrates its 20th anniversary, bringing 20,000 people together. A party train from Cologne also serves as your weekend accommodation! A worthy summer alternative to a party weekend in Berlin.

    “Clothes Swapping”has become an increasingly popular activity for women in the United States. The women can give away unwanted clothing at a clothes swap event and get something different in return.

    Recently about 300 women went to a clothes swap at a high school in Springfield, Virginia. It was the largest crowd ever for the area's popular clothing-swapping group.

    Daphne Steinberg was having a good day.“For anyone who knows Ann Taylor LOFT, Ann Taylor is a really nice women's designer and I will totally wear this to work. So I love that, I love that I can equip myself for work, have a good time in doing it, not totally bankrupt myself.”

Sandy Van Dusen likes the idea that clothes are finding new homes instead of being thrown away. “Because it helps to keep the Earth green. There's no point in my opinion in continuing to buy new clothes when we can reuse what's already here. Give it a new home— let somebody else love what you used to love and no longer love.”

    Kim Pratt organized the clothing-swapping event in Springfield. She also organized a money-raising activity for the high school's debate team. It is one of several ways that her group gives to charitable causes. Another is by donating all of the“un-swapped” clothing to shelters for victims of domestic violence.

    “I started doing this four years ago, and we've been doing it for four years, getting bigger and bigger each time we have a swap.”

    She used the social media website meetup.com to help publicize the events. The website has helped her group grow from 30 members to 1,300. Mrs.Pratt says most of the members respect the clothing swap rules. But she say competition for desirable fashion can be strong.

    “We have to tell people sometimes not to hover over the new people coming in with their clothing. As they put it out, some people tend to grab the stuff right out of their hands and it becomes like a free-for-all. We try to avoid that as much as possible.”

    It was a Sunday and the heavy storm had lasted all night. The morning after the storm, though, was beautiful: blue skies, warm air and a calm, inviting sea touching the shore gently.

    My father realized it was a good day for fishing and invited my sister and me to go with him. I was only 14 and fishing had never been my thing, but I decided to go all the same. I'm so glad I did.

    On the road to the harbour we could see the terrible destruction on the coast, but the harbour itself was in fairly good shape. After all, it was protected by the arms of a bay that had only one tiny channel to the sea. As we got on board, we noticed two big hums(脊背)in the distance.

On approaching them, we saw it was a mother whale with her baby. We couldn't believe it –—there aren't any whales along the coast here. The storm must have driven them across the ocean into the bay, in which the still water was so badly polluted that nothing could survive.

The little baby whale—-actually as big as our boat—-was obviously stuck and could not move. The mother dived under the water and came up suddenly, making big whirlpools(漩涡)and waves. “She's trying to help her baby, but on the wrong side,” my father said. At this point, my father moved our boat in a semicircle to the other side and, heading the boat towards the baby whale, pushed it gently. With our several gentle pushes the big hump turned over and disappeared under water. Then it swam up right beside its mum. They struggled in their desperate attempts to escape but missed the exit and started heading in the wrong direction. We hurried up to the whales and tried to lead them towards the bay channel. Slowly, they let us lead them, sometimes rising from the water right beside us to breathe –—and to give us a trusting(信任的) look with those huge eyes. Once they hit their first part of clean water flowing straight from the sea, the mum gave us a wave with her tail and off they swam into the distance.

    In the excitement it had felt like only a few minutes, but we had been with those wonderful animals for almost an hour and a half. That was the simple and lasting beauty of the day. Nearly four decades later, I still look back fondly to that golden day at sea.

    The flowers are blooming and the birds are singing as Melinda sits in the rose garden of the nursing home. She is recalling old times as she waits for her family's arrival. The nursing home has been Melinda's new settlement ever since Thomas passed away a week ago. Thomas had fought a long and hard battle against lung cancer for three years. Unfortunately, he has broken the promise that he and Melinda had made: to be with each other for every birthday. Melinda knew this was unrealistic (不现实的) but agreed to the promise for Thomas's sake.

    "Thomas, you are completely a dreamerl" Melinda shouted to Thomas as he dragged on about living on an island with his beautiful wife. That's what she loved about him most-he had a vivid imagination. They got married at age eighteen and began having children right away. Mary came within the year, followed by Thomas Benjamin II, Lilly-Ann, and Joseph "Little Joey" George. The family lived an exultant life filled with laughter and love.

    "Mom!" Lilly shouted, but it really sounded like a howl. Melinda had lost herself in thinking about the life she had shared with her late husband. Lilly pushed her down the long dark halls of the nursing home until they arrived at the recreational room.

    When the doors opened, Melinda put her hand over her mouth and was completely speechless. The room was crowded with the people nearest and dearest to her and the warmth and love was felt instantly. The night went on; stories and cocktails were shared and everything was perfect.

    However, when Melinda caught a moment to herself she looked around at her family. With a smile on her face, she raised her Manhattan and called out for a toast. "This one is for you, Thomas, though you are not here."
