Jimmy is an automotive mechanic, but helost his job a few months ago. He has good heart, but always feared applyingfor a new job.

One day, he gathered up all his strengthand decided to attend a job interview. His appointment was at 10 am and it wasalready 8:30. While waiting for a bus to the office where he was supposed to beinterviewed, he saw an elderly man wildly kicking the tyre(轮胎） of hiscar. Obviously there was something wrong with the car. Jimmy immediately wentup to lend him a hand. When Jimmy finished working on the car, the old manasked him how much he should pay for the service. Jimmy said there was no needto pay him; he just helped someone in need, and he had to rush for aninterview. Then the old man said, “Well, I could take you to the office foryour interview. It's the least I could do. Please. I insist.” Jimmy agreed.

    Upon arrival, Jimmy found a long line ofapplications waiting to be interviewed. Jimmy still had some grease on himafter the car repair, but he did not have much time to wash it off or have achange of shirt. One by one, the applicants left the interviewer's office withdisappointed look on their faces. Finally his name was called. The interviewerwas sitting on a large chair facing the office window. Rocking the chair backand forth, he asked, “Do you really need to be interviewed?” Jimmy's heartsank. “With the way I look now, how could I possibly pass this interview?” hethought to himself.

    Then the interviewer turned the chairand to Jimmy's surprise, it was the old man he helped earlier in the morning.It turned out he was the General Manager of the company.

  “Sorry I had to keep you waiting, but Iwas pretty sure I made the right decision to have you as part of our workforcebefore you even stepped into the office. I just know you'd be a trustworthyworker. Congratulations!” Jimmy sat down and they shared a cup of well-deservedcoffee as he landed himself a new job.

    Life is full of funny moments, and not just for humans.

    Over the years, studies by various groups have suggested that monkeys, dogs and even rats love a good laugh. People, meanwhile, have been laughing since before they could talk.

    Jaak Panksepp, a professor at Bowling Green State University, US, said he would not be surprised if positive feelings could be produced in some animals. Dolphins, for example, have long attracted animal researchers because of the complex (复杂的) ways in which they communicate: a rich variety of sounds of different rhythms. A decade ago, researchers studying dolphins at the Kolmarden Wildlife Park in Sweden noticed a set of sounds the dolphins made during play-fighting. They concluded that the purpose of the sound was to suggest that the situation was pleasant and to prevent it from a real fight.

    Panksepp has even seen evidence of joy in crayfish (小龙虾). When given small amounts of drugs such as cocaine (可卡因) in a certain place, they appear to connect that location with pleasure. “Given the chance, they will always return to that place, perhaps in the hope of getting more,” he says. Panksepp wasn't sure it equals the same happiness that humans get from cocaine, but said it “could be in the same evolutionary category”.

    More studies are needed to really understand animals' laughter. Strangely enough, the answers may help with our own desires for cures for mental illnesses. Panksepp's experiments may soon lead to a new antidepressant (抗抑郁) drug that works by using the pathways in the brain behind positive feelings and joy. Perhaps pleasure and laughter in the animal world will help solve the depression in our own species one day.

    Not long ago, I tried convincing my three daughters that the world's secrets are hidden inside silence. The girls looked at me skeptically. Surely silence is nothing?

    Sitting there at the dinner table, I suddenly remembered their curiosity as children, their wondering about what might be hiding behind a door and their amazement as they stared at a light switch and asked me to “open the light”. But now they are 13, 16 and 19 and wonder less and less. If they still wonder at anything, they quickly pull out their smart phones to find the answer. None of them have any interest in discussing with me. To attract their attention, I told them about two friends of mine who had decided to climb Mount Qomolangma.

    Early one morning they left base camp to climb the south-west wall of the mountain. It was going well. Both reached the summit, but then came the storm. They soon realized they would not make it down alive. The first got hold of his pregnant wife by satellite phone. Together they decided on the name of the child that she was carrying. Then he quietly passed away just below the summit. My other friend was not able to contact anyone before he died. No one knows exactly what happened on the mountain in those hours. Thanks to the dry, cool climate 8km above sea level, they have both been freeze-dried. They lie there in silence, looking no different.

    The girls remained quiet, listening. It seemed as though they had got something.

    It is easy to assume that the essence (本质) of technology is technology itself, but that is wrong. The essence is the time we spend with our family and how much freedom we have by technology.

    I have received many Christmas gifts over the years. The best gift I ever received was presented to me by a stranger. I never even knew his name and I only had contact with him for less than 60 seconds. His Christmas present to me changed the way I had thought about people and Christmas.

    It was several years ago when my wife asked me to meet her at the local department store on Black Friday morning. They had advertised a child's bike that she wanted to purchase for our son. We stood with a very large crowd, waiting for the manager to blow the whistle. After a while, the whistle blew. It was like throwing a bucket of fish into a tank of sharks. I told my wife that if we obtained a bike, fine, but we did not, I was OK with that too,

    As the shelf of bikes began to gradually decrease in size, I saw my polite opportunity to wrap my hands around the corner of one of the boxes. I lifted it off the box and suddenly felt some mild resistance. I looked up to see one of the largest gentlemen I had ever seen in my life. Threat was not the word to describe his presence. He was decorated with numerous belts of metal pointed leather around both arms and even his neck. Tattoos(文身) were an obvious passion of his.

    I started to return anxiously the box but he gently pushed it back in my direction and back into my hands. He then directed it into my shopping cart. He look d at me, smiled, and said, “Merry Christmas. ”My wife and I went to the checkout, paid for the bike and went home. All the way home I was thinking that this moment was by far the best Christmas gift I had ever received. The kindness of a stranger that broke all previous views I may have had of stereotypes and prejudices. I will never forget the tenderness of a human heart in a simple act.

    When an earthquake hit a small town，many houses fell down.After the earthquake，all the newspapers reported many stories about some of the families who were in trouble.

    One Sunday，when I was reading a newspaper，a special picture touched me.It gave the clothing sizes of each family member.I thought that this would be a good chance to teach my children to help those who were less lucky than themselves.I said to my seven years old twins，Brad and Brett，and three years old Meghan，"We have so much，and these poor people now have nothing.We'll share what we have with them."

    I filled a box with foods and clothes.While I was doing this, I encouraged the boys to choose their toys and donate some of their less favourite things.Meghan watched quietly as the boys took out their old toys and games and put them together.Then she walked away.A few minutes later she came back with Lucy，her much loved doll.She put the doll on top of the other toys. "Oh, dear," I said. "You don't have to give Lucy.You love her so much."Meghan said，"Lucy makes me happy，Mommy.Maybe she'll make another little girl happy, too."

    I looked at Meghan for a long moment.She taught me a lesson.It's easy to give something that we don't want any more，but hard to give what we cherish(珍爱)，isn't it?

    Like many other people, I love my smart phone, which keeps me connected with the larger world that can go anywhere with me. I also love my laptop, because it holds all of my writing and thoughts. In spite of this love of technology, I know that there are times when I need to move away from these devices and truly communicate with others.

On occasion, I teach a course called History Matters for a group of higher education managers. My goals for the class include a full discussion of historical themes and ideas. Because I want students to thoroughly study the materials and exchange their ideas with each other in the classroom, I have a rule —no laptop, iPads, phones, etc. When students were told my rule in advance of the class, some of them were not happy.

    Most students assume that my reasons for this rule include unpleasant experiences in the past with students misusing technology. There's a bit of truth to that. Some students assume that I am anti-technology. There's no truth in that at all. I love technology and try to keep up with it, so I create to my students.

    The real reason why I ask students to leave technology at the door is that I think there are very few places in which we can have deep conversions and truly engage complex ideas. Interruptions by technology often break concentration and allow for too much dependence on outside information for ideas. I want students to dig deep within themselves for inspiration and ideas. I want them to push each other to think differently and make connections between the course materials and the class discussion.

    I've been teaching my history class in this way for many years and the evaluations reflect students' satisfaction with the environment that I create. Students realize that with deep conversation and challenge, they learn at a level that helps them keep the course materials beyond the classroom.

    I'm not saying that I won't ever change my mind about technology use in my history class, but until I hear a really good reason for the change, I'm sticking to my plan. A few hours of technology-free dialogue is just too sweet to give up.
