I used to believe courtesy(礼貌) was a thing of the past. Very seldom have I encountered a courteous human being in this modem era of the so called Generation X.

    Recently, I had to change my thinking, when I came face to face with just such a human being. I had gone to a happening coffee place, with two of my grown up daughters. The place was crowded with the usual loud crowd and we had to climb a sleep flight of stairs in order to find an empty table. After enjoying coffee and snacks, we were at the steep descent down the stairs, where the narrow space made climbing down only possible in a single file, with hardly any space for another person to either climb up or come down.

    Just as I was in the middle of my descent, a gentleman entered the main entrance of the restaurant which right in front of the staircase. I was sure I would be pushed roughly by this man who will want to go up in a hurry. I kept coming down as fast as I could, holding on to the banister (栏杆), instead of my advanced years. My agile daughters were already down, looking up at me worriedly, hoping I would reach them before the stranger strange started up the stairs, knowing I was a nervous sort.

    Nearly reaching them, I noticed the man still standing near the door. I reached my daughters and passed the stranger at the entrance door which he kept holding open. I looked back thinking he was still at the door, deciding whether to go in or find another less crowded place. I saw him going up the stairs, two at a time. I told my daughters about it and all three of us felt had that we did not even thank the courteous gentleman who was actually holding the door open for us ladies to pass through before going up.

    It's generally believed that people act the way they do because of their personalities and attitudes. They recycle their garbage because they care about the environment. They pay $5 for a caramel brulee latte because they like expensive coffee drinks.

    It's undeniable that behavior comes from our inner dispositions（性情）,but in many instances we also draw inferences about who we are,as suggested by the social psychologist Daryl Bern,by observing our own behavior.We can be strangers to ourselves.If we knew our own minds,why would we need to guess what our preferences are from our behavior?If our minds were an open book,we would know exactly how much we care about the environment or like lattes.Actually,we often need to look to our behavior to figure out who we are.

    Moreover,we don't just use our behavior to learn about our particular types of character—we infer characters that weren't there before.Our behavior is often shaped by little pressures around us,which we fail to recognize.Maybe we recycle because our wives and neighbors would disapprove if we didn't.Maybe we buy lattes in order to impress the people around us.We should not mistakenly believe that we always behave as a result of some inner disposition.

    Whatever pressures there can be or inferences one can make,people become what they do,though it may not be in compliance（符合）with their true desires.Therefore,we should all bear in mind Kurt Vonnegut's advice:"We are what we pretend to be,so we must be careful about what we pretend to be."

    Last summer I got a real taste of Swiss life when I spent six weeks with a host family in the Bernese Alps.

    On arriving in Erlenbach where my host family live,I knew I couldn't have asked for a better setting: it was such a beautiful mountain village.

    And I couldn't have asked for a better host family,either.They made me feel like part of their family,rather than a tourist—I joined in my host family's day-to-day activities,whether helping pick berries in the garden or going to friends' houses.I wasn't only traveling around Europe seeing the major sights,but I lost myself in a different culture.

    While many Swiss cultures are similar to America's,there are lots of differences,too.For example,most Swiss leave their windows open—without screens—all the time.At first I thought all the bugs（虫子）were going to get in and eat me alive,and wondered why they didn't close the windows and turn on the air conditioner.But then I realized there weren't many bugs and I really enjoyed the fresh air.

    Probably my biggest shock was the language.I expected the Swiss to speak German,but they spoke a dialect called Swiss German,which has hardly anything in common with German.At times I was very frustrated（受挫的）because my three years of German did not help,but my bad mood did not last.Anyhow,many people knew English and were extremely willing to speak it.

    Signing up for a cultural exchange was probably the biggest risk I ever took,but it was also the most rewarding. When I left,I promised I would return to Erlenbach.There is more to Switzerland than cheese and watches.

    NOT all memories are sweet. Some people spend all their lives trying to forget bad experiences. Violence and traffic accidents can leave people with terrible physical and emotional scars. Often they relive these experiences in nightmares.

    Now American researchers think they are close to developing a pill, which will help people forget bad memories. The pill is designed to be taken immediately after a frightening experience. They hope it might reduce ,or possibly erase(抹去),the effect of painful memories.

    In November, experts tested a drug on people in the US and France. The drug stops the body releasing chemicals that fix memories in the brain. So far the research has suggested that only the emotional effects of memories may be reduced, not that the memories are erased.

    The research has caused a great deal of argument. Some think it is a bad idea, while others support it.

    Supporters say it could lead to pills that prevent or treat soldiers' troubling memories after war. They say that there are many people who suffer from terrible memories.

    "Some memories can ruin people's lives. They come back to you when you don't want to have them in a daydream or nightmare. They usually come with very painful emotions," said Roger Pitman, a professor of psychiatry at Harvard Medical School. "This could relieve a lot of that suffering."

    But those who are against the research say that changing memories is very dangerous because memories give us our identity (特质). They also help us all avoid the mistakes of the past.

    "All of us can think of bad events in our lives that were horrible at the time but make us who we are. I'm not sure we want to wipe those memories out, "said Rebecca Dresser, a medical ethicist.

    Dearborn Heights, Michigan—2.7 million children under 18 have a parent in prison, and women put in local prisons are the fastest growing population. Shawna Reynolds has seen some of those women up close while working in the corrections system(劳教所) for 17 years, and she was encouraged to try something different.

    After seven years of education and collecting as much money as she could, Shawna created About Face Course Correction—a one-year rehabilitation program(康复项目) that offers a more personal way to help non-violent women prisoners. The program includes classes for women to finish their education, find a job and So on. "You can't expect people who have been in prison to stay in prison," Shawna says. "YOU want them to be helpful people but if you are not going to help them, it's not going to happen."

    The women live free for a year in a house in Dearborn Heights, Michigan. Women like 20-year-old Jennifer Douglas, who dropped out of school, took drugs(吸毒), and has spent years in and out of prison. She says, "I was doing things I would never have thought I would do in my whole life. Because of About Face, Jennifer's life is changing. " "Everyone is starting to trust me again and proud of me and what I'm doing," she says. "It's helped me a lot. It has kept me on the right track."

    There are many other women like Jennifer. Every woman's story is different, but each woman is important. And Shawna is determined to break the cycle and help them turn their lives around. She is using her own money and donations to pay for the house and this program. If you would like to donate, please visit their Go Fund Me account here.
