To understand how Americans think about things, it is necessary to understand "the point". Americans mention it often: "Let's get right to the point." They will say, "My point is…" "What's the point of all this?"

    The "point" is the idea or piece of information that Americans suppose is, or should be, at the center of people's thinking, writings, and spoken comments. Speakers and writers are supposed to "make their points clear", meaning that they are supposed to say or write clearly the idea or piece of information they wish to express.

    People from many other cultures have different ideas about the point. Africans traditionally tell stories that express the thoughts they have in mind, rather than stating the point clearly. Japanese traditionally speak indirectly, leaving the listener to figure out what the point is. Thus, while an American might say to a friend, "I don't think that coat goes very well with the rest of your outfit," a Japanese might say, "Maybe another coat would look even better than the one you have on." Americans value a person who "gets right to the point". Japanese are likely to consider such a person insensitive if not rude.

    The Chinese and Japanese languages are characterized by vagueness and ambiguity. The precision and directness Americans associate with "the point" cannot be achieved, at least not with any grace, in Chinese and Japanese. Speakers of those languages thus have to learn a new way of reasoning and expressing their ideas if they are going to communicate satisfactorily with Americans.

    No one can deny that buttons are an important device. Whenever we see a button, we are eager to press it because we know something will happen. This is true in most cases, for example on a doorbell and on the “on/off” button on the TV. But some buttons are actually fake, like the “close” button on a lift.

    Many people are in the habit of pressing the “close” button because they don't have the patience to wait for the lift doors to shut. But lifts' “close” buttons are a complete scam (骗局), at least in the US － the doors will not close any faster no matter how hard you press.

    It started in the 1990s when the Americans with Disabilities Act was passed in the US, making sure that all lifts stayed open long enough so that people with disabilities could enter. Only US firefighters and repairmen can use the buttons to speed up the door-closing process if they have a code or special keys.

    But to normal lift riders, the buttons aren't completely useless. According to psychologists, fake buttons can actually make you feel better by offering you a sense of control.

     “Perceived (能够感知的) control is very important. It reduces stress and increases well-being,” Ellen J. Langer, a psychology professor, said, “ having a lack of control is associated with depression.”

    Experts have revealed that a lot of buttons that don't do anything exist in our lives for this same purpose. For example, many offices in the US have fake thermostats (温度调节器) because people tend to feel better when they think they can control the temperature in their workspace.

    But psychologists found it interesting that even when people are aware of these little “white lies”, they still continue to push fake buttons because as long as the doors eventually close, it is considered to be worth the effort.

     “That habit is here to stay,” John Kounios, a psychology professor, said. “Even though I have real doubts about the traffic light buttons, I always press them. After all, I've got nothing else to do while waiting. So why not press the button in the hope that this one will work?”

    Young people and older people do not always agree. They sometimes have different ideas about living, working and playing. But in one special program in New York State, adults and teenagers live together in a friendly way.

    Each summer 200 teenagers and 50 adults live together for eight weeks as members of a special work group. Everyone works several hours each day. They do so not just to keep busy but to find meaning and fun in work. Some teenagers work in the forests or on the farms near the village. Some learn to make things like tables and chairs and to build houses. The adults teach them these skills.

    There are several free hours each day. Weekends are free, too. During the free hours some of the teenagers learn photo-taking or drawing. Others sit around and talk or sing. Each teenager chooses his own way to pass his free time.

    When people live together, they should have rules. In this program the teenagers and the adults make the rules together. If someone breaks a rule, the problem goes before the whole group. They talk about it and ask, “Why did it happen? What should we do about it?”

    One of the teenagers has said something about it, “You have to stop thinking only about yourself. You learn how to think about the group.”

    Although his 1-year-old smart-phone still works perfectly, Li Jijia already feels the need to replace it.

    “There are many better ones available now. It's time to upgrade(更新）my phone.”

    Li's impatience is shared by many. Shortly after the season when new products are released（发布，发售）, many consumers feel the urge to upgrade their electronic equipment, even though the ones they have still work just fine.

    As consumers' minds are occupied by Apple's newly released products and debate whether the Google tablet is better than the new Amazon Kindle, it might be time to take a step back and ask: “Do we really need the latest upgrades?”

    According to Donald Norman, an American author, “planned obsolescence (淘汰）” is the trick behind the upgrading culture of today's consumer electronics industry.

    Electronics producers strategically release new upgrades periodically, both for hardware and software, so that customers on every level feel the need to buy the newest version.

“This is an old-time trick—they're not inventing anything new,” Norman said. “This is a wasteful system through which companies--many of them producing personal electronics-- release poor-quality products simply because they know that, in six months or a year, they'll put out a new one.”

    But the new psychology of consumers is part of this system, as Norman admitted, “We now want something new, something pretty, the next shiny thing.” In its most recent year, Apple's profit margin(利润) was more than 21 percent. At Hewlett-Packard, the world's biggest PC maker, it was only 7 percent.

    Apple's annual upgrades of its products create sales of millions of units as owners of one year's MacBook or iPhone line up to buy the newest version, even when the changes are slight.

    As to Li Jijia, the need for upgrading his smart-phone comes mainly from friends and classmates. When they are switching to the latest equipment, he worries about feeling left out.

    “Some games require better hardware to run,” said Li. “If you don't join in, you lose part of the connection to your friends.”

    Technological change is everywhere and affects every aspect of life, mostly for the better. However, social changes brought about by new technology are often mistaken for a change in attitudes.

    An example at hand is the involvement of parents in the lives of their children who are attending college. Surveys (调查) on this topic suggests that parents today continue to be "very" or "somewhat" overly-protective even after their children move into college dormitories. The same surveys also indicate that the rate of parental involvement is greater today than it was a generation ago. This is usually interpreted as a sign that today's parents are trying to manage their children's lives past the point where this behavior is appropriate.

    However, greater parental involvement does not necessarily indicate that parents are failing to let go of their "adult" children.

    In the context (背景) of this discussion, it seems valuable to first find out the cause of change in the case of parents' involvement with their grown children. If parents of earlier generations had wanted to be in touch with their college-age children frequently, would this have been possible? Probably not. On the other hand, does the possibility of frequent communication today mean that the urge to do so wasn't present a generation ago? Many studies show that older parents - today's grandparents - would have called their children more often if the means and cost of doing so had not been a barrier.

    Furthermore, studies show that finances are the most frequent subject of communication between parents and their college children. The fact that college students are financially dependent on their parents is nothing new; nor are requests for more money to be sent from home. This phenomenon is neither good nor bad; it is a fact of college life, today and in the past.

    Thanks to the advanced technology, we live in an age of bettered communication. This has many implications well beyond the role that parents seem to play in the lives of their children who have left for college. But it is useful to bear in mind that all such changes come from the technology and not some imagined desire by parents to keep their children under their wings.

    In Mexico, girls mark their fifteenth birthday with a celebration called Quinceanera. In the morning, the birthday girl goes to the church with her family and her best friends. She wears a beautiful dress. Later in the day, there is a huge party, with a big cake that matches the girl's dress, and a night filled with music and dancing.

    Becoming an adult is a very important life change, and Japan has a special holiday to celebrate this. The second Sunday in January is Coming-of-Age Day. On that day, everyone who had their twentieth birthday in the last year goes to their Town Hall for a special activity. Everyone dresses up, and many women wear beautiful dresses. The mayor makes a speech and gives presents to all the new adults.

    Some kids are afraid to start school, but six-year-olds in Germany can't wait. For them, Schulanfang is a big holiday. To celebrate a child's first day of school, parents or friends give the child a Zuckertuete, a big color box filled with candy and little presents. People take pictures of the kids holding their Zuckertuete, and there is a school party later for the parents with cake and coffee.
