“Don't you have any toys you want to share?” I asked my son during our church's Christmas toy drive. “What about all those things in your closet you haven't used in years?”

    "I don't have anything,” he said. “We're so poor.”

    We're only “poor” because we refuse to buy him the phone he wants for Christmas, which would also require a monthly texting charge.

    “You're not so poor you have nothing to give,” I found myself saying to him, a phrase my mother often used on me.

    At work the next day, one of my students said, “I didn't spell your name right,” as she handed me a Christmas gift—a box of chocolates. No wonder she hadn't spelled it right—I had only worked at the center for a couple of months, and my name is not easy to pronounce, even in English, which is this woman's second language.

    I hadn't expected a gift—I worked at an adult education center, where we dealt with people who struggle economically. When I was hired, my boss told me she tries to keep snacks around the center and cooks “stone soup” once a week, where whoever can bring something in does, because “You will hear growling bellies here. They give their food to the children before they themselves eat.”

    And yet these people, so grateful for a second chance at getting an education, unable to sometimes even afford the gas money to come in, manage to do something for us nearly every week. Some bring in food; others do chores around the center. They help and encourage one another, and us. They give what they are able to give.

    About 70 scientists were working on a very busy project. All of them felt really desperate due to the pressure of work and the demands of their boss but everyone was loyal to him and did not think of quitting their job.

    One day, one scientist came to his boss and told him, “Sir, I've promised to take my children to the exhibition going on in our township so I want to leave at 5:30 p. m.” His boss replied, “OK. You're permitted to leave the office early today.”

    The scientist started working. He continued his work after lunch. As usual, he got involved to such an extent that he looked at his watch only when he felt he was close to completion. The time was 8:30 p. m. suddenly he remembered his promise to the children. He looked for his boss but he was not there. Having told him in the morning himself, he closed everything and left for home. Deep within himself, he was feeling guilty for having disappointed his children. He reached home. The children were not there. His wife alone was sitting in the hall and reading magazines. The situation was explosive; any talk would boomerang on him. His wife asked him, “Would you like to have coffee or shall I straight away serve dinner if you are hungry?” The man replied, “If you would like to have coffee, I too will have but what about the children?” His wife replied, “You don't know? Your boss came here at 5:15 p. m. and has taken them to the exhibition.”

    What had really happened was the boss who gave him permission was observing him working seriously at 5:00 p. m. He thought to himself: this person will not leave the work, but he's promised to take his children to the exhibition. So he took the lead in taking them there. The boss does not have to do it every time. But once it's done, loyalty is established.

    That is why all the scientists at Thumba continued to work under their boss even though the stress was extraordinarily huge. By the way, can you boldly guess who the boss was? He was none other than the mastermind behind India's successful nuclear weapons program, Dr. APJ Abdul Kalam, former president of India.

    People can be addicted to different things, e.g. alcohol, drugs, certain foods, or even television. People who have such an addiction are compulsive, i.e they have a very powerful psychological need that they feel they must satisfy. According to psychologists, many people are compulsive spenders; they feel that they must spend money. This compulsion, like most others, is irrational-impossible to explain reasonably. For compulsive spenders who buy on credit, charge accounts are even more exciting than money. In other words, compulsive spenders feel that with credit, they can do anything. Their pleasure in spending enormous amounts is actually greater than the pleasures that they get from the things they buy.

    There is even a special psychology of bargain hunting. To save money, of course, most people look for sales, low prices, and discounts. Compulsive bargain hunters, however, often buy things that they don't need just because they are cheap. They want to believe that they are helping their budgets, but they are really playing an exciting game: when they can buy something for less than other people, they feel that they are winning. Most people, experts claim, have two reasons for their behavior: a good reason for the things that they do and the real reason.

    It is not only scientists, of course, who understand the psychology of spending habits, but also business people. Stores, companies and advertisers use psychology to increase business: they consider people's need for love, power, or influence, their basic values, their beliefs and opinions, and so on in their advertising and sales methods.

    Psychologists often use a method called “behavior therapy” to help individuals solve their personal problems. In the same was, they can help people who feel that they have problems with money.

    If you get into the forest with your friends, stay with them always. If you don't, you may get lost. If you really get lost, this is what you should do. Sit down and stay where you are. Don't try to find your friends—let them find you by staying in one place.

    There is another way to help your friends or other nearby people to find you. Give them a signal (信号) by shouting or whistling (吹口哨) three times. Any signal given three times is a call for help.

    Keep up shouting or whistling always three times together. When people hear you, they will know that you are not just making noise for fun. They will let you know that they have heard your signal. They give you two shouts, two whistles, or two gun-shots (枪声). When someone gives you a signal, it is an answer to a call for help.

If you don't think that you will get help before night comes, try to make a little house—cover up to the holes with branches (树枝) with lots of leaves. Make yourself a soft bed with leaves and grass.

    What should you do if you get hungry or need drinking water? You would have to leave your little house to look for a river. Don't just walk away. Pick off small branches and drop them as you walk so that you can find your way back. The most important thing to do when you are lost is—stay in one place.

    Doctors in Britain are worried because British teenagers eat lots of fried potatoes, sweets and fat food. Most teenagers don't have enough fruit or vegetables and more than one million British school children are overweight.

    Some teenagers say that they don't have time to eat good food, but kids who have a poor diet often have health problems when they are older.

    Americans have been with fast food for a long time, and it was born there. American fast food is now a part of life far beyond the stores of the United States. McDonald's, Pizza Hut, and KFC have restaurants all over the world.

    No one can say no to the fact that fast food at a fair price has its place around the world. It is popular now, and it is giving a hand to a country's economy (经济).

    A diet of hamburgers, fries and soda may seem happy, but it won't give your body things you need to stay healthy. Fast food has little of many important things our bodies need.

    Some parents are saying no to the fast food restaurants where people eat junk food and doctors are giving young people books and games about a good diet. Having a healthy and well-balanced diet can help you feel better and live longer.

    How was your day today? If it was just sort of OK, with nothing much happening, then Scott Shaffer wants to hear from you. Mr Shaffer is the editor of the Journal of Mundane Behaviour. "We can learn a lot about the way that society works by examining normal patterns of behavior," he says. "All the ordinary decisions we make and ordinary things we do are society in action."

    The idea that social scientists should "study the unmarked", in Mr Shaffer's words, has also spread to historians. Traditionally, most history has been written as the story of greatness. It is all about great ideas, great people and great economic and social forces changing the way that millions of people live for ever. Albert Einstein's theory of relativity changed the way that we look at the universe. But has he been of more benefit to humanity than the unknown person who invented the first really comfortable shoe? Try thinking great thoughts when your feet hurt.

    In recent years, books of micro-history have been a great success with the public. Most micro historians like to relate their subject to wider developments in society. According to historian Catherine Gallagher, the potato was once a matter of great argument. Supporters pointed out that it could grow cheaply and easily and help feed the poor. Opponents said that this would lead to the poor becoming more powerful, since they did not have to spend every hour working to feed themselves. It seems that European socialism started with an argument about vegetables. British historian Colin Jones wants us to look at pictures painted hundreds of years ago. He wants us to notice the fact that nobody smiles in these pictures. Compare that with today, when everyone smiles for the camera and refusing to smile is seen as an unfriendly act. It is all because of dentistry, he says. Once people were able to look after their teeth, they began to smile and the world became a happier place.

    Whether stories like this are true or not, they put ordinary people at the center of history. Most of us are not going to change the world in a big way. But we might be able to do something that makes life a bit easier for other people. And maybe one day a historian will come along and write the story. It is something to get excited about, though perhaps not very excited.
