In a foreign country, a man visited a local restaurant. He didn't speak their language. He ordered something indecipherable off the menu. When the waiter brought him a plate of delicious looking fried noodles, he smiled and made an OK sign at the waiter with his thumb and forefinger linked in a circle. Looking angry, the waiter then picked up the dish and thrown it to his lap. What he did wrong, he wondered. Well, nothing is quite as it seems when it comes to using hand gesture in another country.

    Gestures have been used to replace words in many countries, and they are often specific to a given culture. Gesture may mean something complimentary in one culture, but is highly offensive in another.

    The gesture “thumb-up” is commonly misinterpreted. In English, it is popularly known as 'thumbs up', despite the fact that the action is commonly performed with only one hand. English-speaking Caucasians use it to signal 'OK', which is the same meaning as O.K. ring gesture. The two can in fact be used almost interchangeably.

    Avoid using this gesture in Southern Sardina or Northern Greece unless you want to invite a fight. While American, British and Australian would use the thumb up to signal hitch-hiking to the drivers, this message will not encourage a Greek driver or motorist to stop to give them a ride.

    There are no right or wrong signals, only cultural differences. Lack of cultural understanding will lead to disharmony among people from different cultures. When we know what to look for, such encounters with other cultures are actually very interesting, fascinating and fun. It is certainty a great topic to discuss over a cup of coffee and cakes.

    According to a new study ,a smiley face emoji（笑脸符）in work-related e-mails may not create a positive impression and could even weaken information sharing. In formal business emails, a smiley is not a smile.

    In one of the experiments, people were asked to read a work-related e-mail from an unknown person and then tell about both the ability and warmth of that person. Before that, they all received similar messages. But some included smileys while others did not. The results suggested that contrary to face-to-face smiles, which increase both ability and warmth, the smileys in a business e-mail had no effect on the perception（感知）of warmth, and in fact had a bad effect on the perception of ability. The perceptions of low ability in turn weakened information sharing.

    In another experiment, the use of a smiley was compared to a smiling or neutral photograph. The findings showed that in the case（情况）of a photograph, a smiling sender was judged to be more able and friendly than a neutral one. However, when an e-mail on formal work-related maters included a smiley, the sender was thought to be less able. The smiley did not influence the opinion on the sender's friendliness.

    “People are easy to accept that a smiley equals a real smile, but the findings of this study show that in the workplace, this seems not the case, especially when first communications are concerned.” Dr. Glikson says. “In such a situation, it is better not to use smileys to people at whatever age. Smileys could hardly be a wise choice to a person you are not familiar with.”

    One of the greatest sources of unhappiness, in my experience, is the difficulty we have in accepting things as they are.

    When we see something we don't like, we wish it could be different. We cry out for something better. That may be human nature, or perhaps it's something ingrained(根深蒂固的) in our culture. The root of the unhappiness isn't necessarily that we want things to be different. However, it's that we decided we didn't like it in the first place. We've judged it as bad, rather than saying, "It's not bad or good, and it just is it."

    In one of my books, I said "You should expect people to mess up and expect things to go differently than you planned". Some readers said it's too sorrowful to expect things to go wrong. However, it's only negative if you see it as negative and judge it as bad. Instead, you could accept it as the way the world works and try to understand why that is.

    This can be applied to whatever you do: how other people act at work, how politics works and how depressing the news media can be. Accept these things as they are, and try to understand why they're that way. It will save you a lot of sadness, because you'll no longer say, "Oh. I wish bad things didn't happen!"

    Does it mean you can never change things? Not at all. But change things not because you can't accept things as they are, but because you enjoy the process of changing, learning and growing.

    Can we make this world a better place? You can say that you'll continue to try to do things to help others, to grow as a person, to make a difference in this world. That's the correct path you choose to take, because you enjoy that path. Therefore, when you find yourself judging and wishing for difference, try a different approach: accept, and understand. It might lead to some interesting results.

    The idea of progress started to flower in the 17th century. At that time, many wise thinkers believed that man liberated（解放） by reason would rise to greater heights of achievement. The many expressions of human nature would be the engines of progress: language, business, science, and moral sensibility （道德感）. Unfortunately, most of those engines have failed to bring the desired human progress.

    The modern age has belonged to material progress and its main source has been science. Science gives people huge power to change the world. But can people be trusted to use it always for good? Think of biotechnology and information technology. And it is not just that scientific progress does not deliver the emotional good. People also fear that mankind is failing to manage science properly. The forests are disappearing; the ice is melting; privacy is leaking; life is becoming a depressing march in an ugly world.

    The point is not that science is harmful, but that scientific progress needs to be mapped tidily onto human progress. That relies on moral sensibility in its widest sense. This liberal force offers hope for a better future. The very idea of moral sensibility probably sounds out-of-date. Bur researchers find that people desire a sense of moral purpose which would give life dignity （尊严）. People want to determine how the world works, not always to be determined by it. Moral sensibility is why people will suffer from their beliefs, and why acts of noble self﹣sacrifice are so powerful.

    It is admitted that our moral ideals will never be realized completely. But sometimes, however imperfectly, we can make progress. Human dignity requires the love of ideals for their own sake, but nothing requires that the love be returned.

Human progress is neither guaranteed nor hopeless. Instead, it is up to us.

    After years of trying, our neighbors convinced my parents that ice fishing would be a fun winter getaway from our dairy farm. Before that, their idea of entertainment involved driving around the countryside to see how the neighbors' crops were doing.

My parents eventually built a fish house and set it up on Wood Lake. We excitedly headed for the lake on many January and February weekends. By the time we arrived at our favorite fishing spot across the lake each day, somebody had usually made a clear path across the ice. The fish houses were together at the best fishing spots, forming some kind of a neighborhood.

    Our house was large enough so all four of us could fish at the same time. Each corner had a square cut out of the floor. We sat in comfort. You'd think ice fishing would be cold, but we had a small woodstove (木炉) inside, and we put snow around the bottom of the house to keep the wind from blowing underneath.

    Besides the thrill of watching your bobber (钓鱼浮标) dip below the water, lunch was always the highlight of the day. Mom would fry pork or hamburgers in a pan. The smell of cooking meat was the envy of every other fish house in the neighborhood.

    Our days passed with a mix of quiet time and family chatter. We talked about the farm or school. And of course, we shared fishing advice. Part of the fun of ice fishing was learning to understand and trust the sounds of the frozen lake. Healthy ice "talks" as it freezes and shifts. You could often hear the sound of a crack traveling through the ice.

    People who have never tried ice fishing may not think it sounds very exciting, but it was for us. Fishing trips were an adventure. We didn't always catch fish, but we always brought home great memories of a day with family and friends.

All animals play. Runing, rolling and wrestling with each other is a way for them to have fun, of course. But it also seems to be how they communicate and strengthen bonds with each other.

When a dog comes up to another dog, front legs bowed and his tail high, his buddy knows he wants to play. But new research shows that this play behavior is surprisingly similar when horses and dogs play.

To study interspecies communication, Elisabetta Palagi and her colleagues from the University of Pisa found 20 YouTube videos of dogs and horses playing where their interactions lasted at least 30 seconds. They analyzed the videos, looking for specific pattern of play.

They found that while playing, both dogs and horses often had relaxed, open mouths-which is common playful facial expression in mammals. Some also copied each other's movements, like pretending to bite, playing with an object, or rolling on their backs on the ground. A 2,000-pound horse can play with a relatively tiny dog because the two are able to communicate their intentions.

"It's an important study because it shows how two animals who look and behave so differently can nevertheless manage to negotiate how to play in a way that's comfortable for both," Barbara Smuts, a behavioral ecologist at the University of Michigan, told National Geographic.

It's even more noteworthy given the large size difference between horses and dogs. The dog is vulnerable (易受伤的) to injury by the horse, and the horse has a deeply rooted tendency to fear animals that look like wolves."

Next up, the researchers write, is exploring the development and shaping of interspecies communication that “can be at the basis of a universal language of play".
