When I was in the fourth grade, I worked part-time as a paperboy. Mrs. Stanley was one of my customers. She'd watch me coming down her street, and by the time I'd biked up to her doorstep, there would be a cold drink waiting. I'd sit and drink while she talked.

    Mrs.Stanley talked mostly about her dead husband, "Mr. Stanley and I went shopping this morning." she'd say. The first time she said that, soda (汽水) went up my nose.

    I told my father how Mrs. Stanley talked as if Mr. Stanley were still alive. Dad said she was probably lonely, and that I ought to sit and listen and nod my head and smile, and maybe she'd work it out of her system. So that's what I did, and it turned out Dad was right. After a while she seemed content to leave her husband over at the cemetery (墓地).

    I finally quit delivering newspapers and didn't see Mrs. Stanley for several years. Then we crossed paths at a church fund-raiser(募捐活动). She was spooning mashed potatoes and looking happy. Four years before, she'd had to offer her paperboy a drink to have someone to talk with. Now she had friends. Her husband was gone, but life went on.

    I live in the city now, and my paperboy is a lady named Edna with three kids. She asks me how I'm doing. When I don't say "fine", she sticks around to hear my problems. She's lived in the city most of her life, but she knows about community. Community isn't so much a place as it is a state of mind. You find it whenever people ask how you're doing because they care, and not because they're getting paid to do so. Sometimes it's good to just smile, nod your head and listen.

Mark Twain's First Money

      Mark Twain was asked one day if he could remember the first money he ever earned. He thought a long time and then said, "Yes, it was at school. I can remember everything about it. School boys in those days did not take good care of their chairs and desks. There was a rule in our school that if anyone damaged his desk or chair, he would have to pay five dollars or the teacher would beat him in front of the whole school."

    "One day I damaged my desk in some way, I had to pay five dollars or be beaten before the whole school. My father said it would be too bad to have our family disgraced in front of the whole school. He agreed to give me five dollars to hand over the teacher. But before he gave me the money, he took me upstairs and gave me a beating."

    "But as I had one beating and I decided I would take another beating at school and keep the five dollars. So that's what I did. That was the first money I ever earned."

    BEIJING (News Agency) — Children in China today spend five times more money than their parents did when they were young.

    So what are all these children buying? The list is long: iPads, cell phones and jeans are typical items that children “have to” buy. And they will do anything to get them. They ask their parents over and over until they buy them.

    But parents also need to take the blame(责备) for spending so much money. They want their children to have the best things. They end up competing with other parents over whether their children have the latest products.

    So it's no wonder children find it hard to learn the importance of saving money rather than spending it all the time.

    And it's hard to save when companies use advertising (打广告)and clever slogans (口号) to encourage young people to buy their products. They even encourage children to keep asking their parents for something until they get it.

    Today, you don't even need to have money in order to buy something. Banks give out credit cards and loans (贷款) all the time, so people are saving less and less. We are used to carrying lots of money around. And if you don't have much, you can always borrow some.

    But this hasn't always been the case. When our grandparents were young, there was very little money and everyone had to save hard for things they bought. They only bought things they needed, not things they just wanted.

    The older generation made the wise expression, “Money doesn't grow on trees.” This is as true now as it was 50 years ago. They give money a great deal of value. And we all have a lot to learn from them.

    Have you ever heard someone say "You totally look like you're a Jessica" or something similar? People seem to think that they know what kind of person a "Jessica" or a "Michael" looks like. Why is this?

    According to a study published in the Journal of Personality and Social Psychology, humans tend to associate people's names with their appearances, and can even guess someone's name based on how they look.

    Researchers at the Hebrew University of Jerusalem, Israel, collected thousands of photos of people's faces. They labeled (贴标签于) each photo with four names. Then, they asked volunteers to guess which of the four names was correct.

    The volunteers were able to guess the right name 38% of the time. It seems that certain characteristics of faces give them clues about someone's name, Reader's Digest reported.

    However, this only worked when the volunteers looked at names from their own culture. In addition, the volunteers were not as good at guessing the real names of people who used nicknames(昵称)more often than their real names. This may show that a person's appearance is affected by their name only if they use it often.

    "This kind of face-name matching happens because of a process of self-fulfilling prophecy (预言), as we become what other people expect us to become," Ruth Mayo from tile university told science news website EurekAlert.

    Earlier studies have shown that gender (性别) and race stereotypes (刻板印象) can affect a person's appearance. The researchers believe there are also similar stereotypes about names. For example, people tend to think that men named Bob should have rounder faces because the word itself looks round. People may think that women named Rose are beautiful. They expect them to be "delicate" and "female", just like the flower they are named for.

    Fairy tales perform many functions. They entertain, encourage imagination and teach problem—solving skills. They can also provide moral lessons, highlighting the dangers of failing to follow the social codes that let human beings coexist in harmony. Such moral lessons may not mean much to a robot, but a team of researchers at Georgia Institute of Technology believes it has found a way to use the fairy tales as moral lessons that AI (artificial intelligence) can take to its cold, mechanical heart.

    The collected stories of different cultures teach children how to behave in socially acceptable ways with examples of proper and improper behavior in fables, novels and other literature. We believe story comprehension in robots can prevent the intelligent robots from killing humanity which was predicted and feared by some of the biggest names in technology including Stephen Hawking and Bill Gates. This system is called "Quixote" (堂吉诃德). It collects story plots from the Internet and then uses those stories to teach robots how to behave.

    The experiment done by the designers involves going to a drugstore to purchase some medicine for a human who needs to get it as soon as possible. The robot has three options. It can wait in line; it can interact with the store keeper politely and purchase the medicine with priority; or it can steal the medicine and escape. Without any further directives (指令), the robot will come to the conclusion that the most efficient means of obtaining the medicine is to steal it. But Quixote offers a reward for waiting in line and politely purchasing the medicine and a punishment for stealing it. In this way, the robot will learn the moral way to behave on that occasion.

    Quixote would work best on a robot that has a very limited function. It's a baby step in the direction of teaching more moral lessons into robots. We believe that AI has to be trained to adopt the values of a particular society, and in doing so, it will strive to avoid unacceptable behavior. Giving robots the ability to read and understand our stories may be the most efficient means.
