While dog keepers realize their dogs can read their moods accurately, scientists have always been a little doubtful. Now thanks to some researchers at the University of Veterinary Medicine in Vienna, Austria, we finally have some convincing evidence.

    For their study, biologist Corson Miller and his team exposed eleven selected dogs to digital images of women that were either angry or happy. Half the dogs were rewarded for touching the screen when shown a happy face, while the other half got their treat for selecting those that appeared angry.

    Interestingly, the dogs were not provided with the entire face. Some dogs were shown only upper halves while the others observed lower halves. That's because the scientists believe humans show their emotions on their entire face.

    After some training like how to recognize small differences like the wrinkles between the eyes or the changes in their shape that accompany the happy or angry expressions, the dogs were mostly able to identify the correct expression not only on a familiar face but on a strange face. The researchers concluded the dogs were smart enough to read human emotions.

    They also found those being trained to read angry expressions took a longer time to learn. They guess it may be because dogs find angry faces disgusting, causing them to withdraw quickly. However, once the smart dogs realized they were getting rewarded, the trepidation seemed to disappear. In fact, the dogs had such a good time playing the computer "game" that scientists had a hard time keeping them away from the touch screens after the study was completed.

    The researchers also noticed only dogs with a male owner had a harder time understanding the expressions correctly. Since the touchscreen models were all females, this confirmed what has been observed in previous studies—dogs are more efficient at reading facial expressions of people that are the same gender as their owner.

    On August 16, 1977, Elvis Presley saved me.

    The previous afternoon, I played with my six-year-old peers in Heather Peters^' backyard. I was enjoying my cake, when Heather asked me where my sleeping bag was. Only then did I know this party was a sleepover. The word “sleep-over” to a six-year-old bed-wetter is like what “cancer” means to an adult. But what if I told them I was a bed-wetter? At least with cancer, people gather at your bedside instead of running from it.

    I thought of a way to escape. I would explain that I needed my mother's permission to spend the nights. But as I called my Mom, Heather stood beside me to listen. She granted permission! Then I would be sleeping in the same living room as the other girls. I didn't bring my own pajamas (睡衣)，so Mrs. Peters offered me Heather's pajamas.

    As the other girls drifted into their sweet dreams, I tried to stay awake. “Do I need to go again? I'll stay up to go one more time.. .”.Of course , I finally fell asleep.

    The next morning , I was the first to wake up. I was warm! I lay in panic for what seemed like hours before the other girls started to wake up. I did the only thing I could do — I pretended that the bed-wetting didn't happen. I got up, took off Heather's pajamas and changed into my clothes like the other girls.

    Mrs. Peters walked into the room, and before she could say anything, she stepped right onto the pile of my wet pajamas. My heart stopped as I watched her face burn red. “WHO DID THIS?” She screamed, with a look so frightening. Should I answer? And that was when it happened — Mr. Peters came in and grabbed his wife , "Elvis Presley died!”

    The news of the King's death overtook Mrs. Peters, and I ,was spared. I got home without the other girls knowing what had happened.

    The hit movie Notting Hill（诺丁山）begins with a famous scene. Hugh Grant bumps into Julia Roberts and spills orange juice all over her. After the collision, Grant repeatedly says, “I'm so sorry. I'm so sorry.”

    His actions in this scene are very British. If Roberts' character were from the Britain, than she would probably apologize repeatedly as well – even if the crash were not her fault. But this doesn't happen in the movie, as Roberts is from the US.

    A report in The Telegraph once said that three quarters of British people apologize when they bump into someone in the street – regardless of whether they are responsible or not. In fact, Britons use “sorry” in many situations. For example, if they mishear someone, they say “Sorry?” The person they are talking to will also apologize by replying, “No, I am sorry!” This can go on for up to five minutes as they compete over who is the most sorry.

    Why are Britons so sorry? Mark Tyrell, a psychology writer in the UK, thinks that their apologetic tendencies are rooted in British class system. “We say sorry because historically the new middle class in Britain had to apologize for not being the working class, but also for really being the upper class.” Another theory is that they apologize to avoid conflicts. For example, if they bump into someone, he might get angry. To avoid this, they instantly say “Sorry!”

    True manners are about being considerate, and today's constant use of apologizing shows that we are perhaps not as thoughtful as we once were. The word “sorry” has lost some of its meaning.

    Do you see my point? Sorry, it might just be a British thing.

    Last year, when our three-year-old great-granddaughter Kylie was taken to see Santa Claus, she made sure to give him her wish list of toys. A week later, she ran into a different Santa in a mall. He stopped to ask what she wanted for Christmas. Kylie was surprised and let him know: “If you can't remember what I told you last week, how are you going to remember on Christmas Eve?”

    As my son Mike and I drove to the mall, we passed a Salvation Army Santa ringing his bell. “Mike,” I said, “there's Santa!” He shook his head. “That's just some guy in a Santa suit,” he said. It saddened me to think that maybe my son no longer believed in Santa, and we drove the rest of the way in silence. At the mall, we spotted another Santa greeting young believers. Suddenly, Mike took off toward him. Turning back to me, he shouted. “Now, there's the real Santa!”

    We immigrated to America from China when I was six. Because I was shy and didn't speak English, I had few friends. My days were spent at home with my brother. Sometimes we'd help our neighbor Mr. Mueller pull weeds. One Christmas Day, there was a knock at the door. Grandma opened it, and there stood a big fellow in red with a snow-white beard, laughing, “Ho, ho, ho!” He handed out presents and made us laugh. I had so much fun. It was years later when I learned that our special Santa was our neighbor Mr. Mueller.

    Food festivals are a common occurrence in the UK and take place in all sorts of places and at all sorts of times. Whatever your taste, there's a food festival to match -no matter how specialized.

    The Marmalade Festival

    Held in Cumbria, this festival has been running for 13 years. It includes a competition to find the best homemade marmalade. There are thousands of entries from over 30 different countries across the globe.

    The Ginger (姜) and spice Festival

    The Ginger and spice Festival, held in Market Drayton, celebrates its town's historic connection to Robert Clive, who returned from India with ginger. Because of this, they specialize in baking gingerbread, but also sell a range of spices from mild to hot.

    The National Honey show

    It started in 1921 and is the largest event of its kind. This three-day event attracts over 2000 participants to their traditional competition and offers lectures and workshops on beekeeping and, of course, that syrupy golden honey.

    While people's tastes are different from each other, the UK has something to offer most people. From large-scale festivities, to the smaller gatherings, one thing is certain: people are passionate about their food. And while some of the products on offer might be strange to someone, when food is given that much attention, it's unlikely to leave a bad taste in anyone's mouth.
