For years now, I've been wanting to sell our house, the place where my husband and I raised our children. But to me, this house is much more than just a building.

    In the front room, there's a wall that has hundreds of pencil lines, marking the progress of my children's growth. Every growth stage is marked in grey, with each child's name and the date when they were measured. Most people I know have been featured on a wall like this, or at least had a wall like it in their home.

    Of all the objects and memories, it is this thing in a home that is the hardest to leave behind. Friends I know have returned home after work only to discover their wall of heights has been freshly painted over. A new paint job wouldn't normally be greeted by tears, but erasing that evidence of motherhood hurts more than it should. Our children grow in so many ways, but the wall is the physical evidence of their progress, right there for everyone to see.

    Over the years, I've talked about how much I would hate leaving that wall behind when I moved, even though the last marks were made 10 years ago when my children stopped growing.

    So one day, while I was at work, my children decided to do something about it. They hired Jacquie Manning, a professional photographer. She came to our house, and over several hours, took photos of the hundreds of drawings and lines, little grey fingerprints and old marks. Somehow, she managed to photograph all those years of memories perfectly. Afterwards, she put all the photos together into one image, changing them into a beautiful history of my family.

    Three weeks later, my children's wonderful gift made its way to me — a life-size photo of the pencil lines and fingerprints that represents an entire lifetime of love and growth.

    Atlantic puffins（角嘴海雀）are specially used to living on the open sea. Their feathers allow them to stay warm as they float at the ocean's surface or swim underwater. Diving as deep as 60m, they swim by flapping their wings as if flying through the water. There, they hunt herring, capelin, and sand eels.

    Atlantic puffins are also excellent fliers. Flapping their wings at up to 400 beats per minute, puffins can reach speeds of 88km/h.

    April to mid-August is the breeding season for puffins. When a puffin is around three to five years old, it will choose a partner at sea to mate with for life. It is thought that the birds' colourful bills and feet, which fade in the winter and brighten in the spring, help puffins find their potential（可能的）mates.

    Puffins create shelter（庇护所）, about 90cm, in rocky cliffs either in the soil or between rocks. Often, couples will return to the same shelter year after year. At the back of the shelter, they build a nest lined with grasses, seaweed, and feathers. After the female lays a single egg, both parents take turns incubating（孵化）the egg for about 40 days.

    Once the chick hatches, the mother and father will take turns bringing it fish to eat several times a day. Atlantic puffins have the ability to carry several fish in their beaks at one time. The ridges（脊）at the top of their bill hold the fish in place, which allows puffins to keep their mouth open to catch more fish without losing any. In general, they can hold around ten fish in their beak at one time.

    In the wild, puffins can live around 20 years. Their main predator is the great black-backed gull, which can capture a puffin mid-flight or attack a puffin on the ground. Gulls are also a threat because they steal puffins' fish (sometimes right from their mouths), and they pull puffin chicks or eggs from their nests.

    Imagine looking at yourself in the mirror; you do not look like these stick -thin models seen across the media. Your legs are too big, your bottom is too small, and you are too pale. You are too “ugly” You stare in wonder and anger, “Why don't I look like them?" However, you don't need to imagine this situation, because this is a bitter truth for millions of people. In the media，one can quickly see the ideal body, the ideal face, and the ideal person. The advancement of unrealistic beauty on social media causes millions of people to become dissatisfied with their looks.

    Dissatisfaction with one's appearance can cause dangerous behaviors like dieting, which result in eating disorders like Anorexia Nervosa (神经性厌食症) and Bulimia Nervosa (神经性易饿病). Eating disorders have seen a dramatic increase following the rise of social media, 119% increase according to recent statistics. According to Brittany Tackett, a mental health professional,“30% -50% of patients in eating disorder hospitals used social media as a means of supporting their eating disorders.”

    Not only can social media become a support-system for unhealthy behaviors, but an article written by Rachel Simmons, a Time magazine writer, suggests that people who spend more time online tend to link their self-worth to their looks. A study conducted by Park Nicollet Melrose Center also says that in the 1990's, fifty-percent of women wanted to lose weight. Now it finds that eighty-percent of women want to lose weight. Although this higher percentage cannot be directly related to the rise of social media, one can argue that the unrealistic and damaging beauty expectations that social media presents contribute to this number.

    In addition, social media causes stress. A survey was conducted in which people were asked whether or not they used social media, and how stressed they felt they were. The study found that “social network users are, in fact, 14 percent more likely than non-users to characterize their lives as at least 'somewhat stressful.' Non-users are 28 percent more likely than users to say their lives are 'not at all' stressful”. Additionally, stress may have more connection to self-confidence than is believed.

    So，there you are again, standing in front of the mirror criticizing the parts of your body which do not follow the idealistic images of models seen on social media. Your legs are too big, your bottom is too small, and you are too pale. You are too “ugly”. Although this time, you realize it is not you who are the problem. The problem is the unhealthy and unrealistic standards that social media encourages. So the next time you are looking through Instagram, opening WeChat, or commenting on Twitter, ask yourself, “Is it worth it?”

    According to a recent survey on money and relationships, 36% of people are keeping a bank account from their partner. While this financial unfaithfulness may appear as distrust in a relationship, in truth it may just be a form of financial protection.

    With almost half of all marriages ending in divorce, men and women are realizing they need to be financially savvy, regardless of whether they are in a relationship.

    The financial hardship on individuals after a divorce can be extremely difficult, even more so when children are involved. The lack of permanency in relationships, jobs and family life may be the cause of a growing trend to keep a secret bank account hidden from a partner, in other words, an "escape fund".

    Margaret's story is far from unique. She is a representative of a growing number of women in long-term relationships who are becoming protective of their own earnings. Every month on pay day, she banks hundreds of dollars into a savings account she keeps from her husband. She has been doing this throughout their six-year marriage and has built a nest egg worth an incredible $100,000. Margaret says if her husband found about her secret savings he'd be hurt and would take this as a sign that she wasn't sure of the marriage. "He'd think it was my escape fund so that financially I could afford to get out of the relationship if it went wrong. I know you should approach marriage as being forever and I hope ours is, but you can never be sure."

    Like many of her fellow secret savers, Margaret was hurt in a former relationship and has since been very guarded about her own money.

    Coming clean to your partner about being a secret saver may not be all that bad. Take Colleen for example, who had been saving secretly for a few years before she confessed (坦白) to her partner. "I decided to open a savings account and start building a nest egg of my own. I wanted to prove to myself that I could put money in the bank and leave it there for a rainy day."

    Editor: Today our topic is part-time job. Are they good for school children or not?

    Headmaster: Certainly not. Children have got two full-time jobs already: growing up and going to school. Part-time jobs make them so tired that they fall asleep in class.

    Mrs. White: I agree. I know school hours are short, but there's homework as well, and children need a lot of sleep.

    Mr. White: Young children, perhaps some boys, stay at school until they're eighteen or nineteen. A part-time job can't harm them. In fact, it's good for them. They earn their pocket money instead of asking their parents for it. And they see something of the world outside school.

    Businessman: You're quite right. Boys learn a lot from a part-time job. And we mustn't forget that some families need the extra money. If the pupils didn't take part-time jobs, they couldn't stay at school.

    Editor: Well, we have got two for, and two against. What do our readers think?

By now you've probably heard about the "you're not special" speech, when English teacher David McCullough told graduating seniors at Wellesley High School: "Do not get the idea you're anything special, because you're not." Mothers and fathers present at the ceremony — and a whole lot of other parents across the Internet — took issue with McCullough's ego-puncturing words. But lost in the uproar was something we really should be taking to heart: our young people actually have no idea whether they're particularly talented or accomplished or not. In our eagerness to elevate their self-esteem, we forgot to teach them how to realistically assess their own abilities, a crucial requirement for getting better at anything from math to music to sports. In fact, it's not just privileged high-school students: we all tend to view ourselves as above average.

Such inflated self-judgments have been found in study after study, and it's often exactly when we're least competent at a given task that we rate our performance most generously. In a 2006 study published in the journal Medical Education, for example, medical students who scored the lowest on an essay test were the most charitable in their self-evaluations, while high-scoring students judged themselves much more strictly. Poor students, the authors note, "lack insight" into their own inadequacy. Why should this be? Another study, led by Cornell University psychologist David Dunning, offers an enlightening explanation. People who are incompetent, he writes with coauthor Justin Kruger, suffer from a "dual burden": they're not good at what they do, and their very incapability prevents them from recognizing how bad they are.

In Dunning and Kruger's study, subjects scoring at the bottom of the heap on tests of logic, grammar and humor "extremely overestimated" their talents. What these individuals lacked (in addition to clear logic, proper grammar and a sense of humor) was "metacognitive skill": the capacity to monitor how well they're performing. In the absence of that capacity, the subjects arrived at an overly hopeful view of their own abilities. There's a paradox here, the authors note: "The skills that lead to competence in a particular domain are often the very same skills necessary to evaluate competence in that domain." In other words, to get better at judging how well we're doing at an activity, we have to get better at the activity itself.

There are a couple of ways out of this double bind. First, we can learn to make honest comparisons with others. Train yourself to recognize excellence, even when you yourself don't possess it, and compare what you can do against what truly excellent individuals are able to accomplish. Second, seek out feedback that is frequent, accurate and specific. Find a critic who will tell you not only how poorly you're doing, but just what it is that you're doing wrong. As Dunning and Kruger note, success indicates to us that everything went right, but failure is more ambiguous: any number of things could have gone wrong. Use this external feedback to figure out exactly where and when you screwed up.

If we adopt these strategies — and most importantly, teach them to our children — they won't need parents, or a commencement (毕业典礼) speaker, to tell them that they're special. They'll already know that they are, or have a plan to get that way.
