I first came across the concept of pay-what-you-can cafes last summer in Boone, N.C., where I ate at F.A.R.M (Feed All Regardless of Means) Café. You can volunteer to earn your meal, pay the suggested price($10) or less, or you can overpay—paying it forward for a future customer's meal. My only regret after eating there was not having a chance to give my time. So as soon as Healthy World Café opened in York in April, I signed up for a volunteer shift(轮班).

    F.A.R.M and Healthy World are part of a growing trend of community cafés. In 2003, Denise Cerreta opened the first in Salt Lake City. Cerreta now runs the One World Everybody Eats Foundation, helping others copy her pay-what-you can model.

    “I think the community café is truly a hand up, not a handout,” Cerreta said. She acknowledged that soup kitchens(施粥所) have a place in society, but people typically don't feel good about going there.

    “One of the values of the community café is that we have another approach,” she said. “Everyone eats here, no one needs to know whether you volunteered, overpaid or underpaid.”

    The successful cafés not only address hunger and food insecurity but also become necessary parts of their neighborhood – whether it's a place to learn skills or hear live music. Some teach cooking to seniors; some offer free used books. Eating or working there is a reminder that we are all in this world together.

    My 10 am—1pm shift at World-Healthy-Café began with the café manager — one of the two paid staff members. Our volunteer crew wasn't the most orderly, but we managed to prepare and serve meals with a lot of laughs in between. At the end of my shift, I ordered my earned meal at the counter, together with other volunteers. After lunch, I walked out the door, with a handful of new friends, music in my head and a satisfied belly and heart.

    Adults understand what it feels like to be flooded with objects. Why do we often assume that more is more when it comes to kids and their belongings? The good news is that I can help my own kids learn earlier than I did how to live more with less.

    I found the pre-holidays a good time to encourage young children to donate less-used things, and it worked. Because of our efforts, our daughter Georgia did decide to donate a large bag of toys to a little girl whose mother was unable to pay for her holiday due to illness. She chose to sell a few larger objects that were less often used when we promised to put the money into her school fund(基金）(our kindergarten daughter is serious about becoming a doctor)

    For weeks, I've been thinking of bigger, deeper questions: How do we make it a habit for them? And how do we train ourselves to help them live with, need, and use less? Yesterday, I sat with my son, Shepherd, determined to test my own theory on this. I decided to play with him with only one toy for as long as it would keep his interest. I expected that one toy would keep his attention for about five minutes, ten minutes, max. I chose a red rubber ball-simple, universally available. We passed it, he tried to put it in his mouth, he tried bouncing it, rolling it, sitting on it, throwing it. It was totally, completely enough for him. Before I knew it an hour had passed and it was time to move on to lunch.

    We both became absorbed in the simplicity of playing together. He had my full attention and I had his. My little experiment to find joy in a single object worked for both of us.

Why College Is Not Home

    The college years are supposed to be a time for important growth in autonomy(自主性) and the development of adult identity. However, now they are becoming an extended period of adolescence, during which many of today's students are not shouldered with adult responsibilities.

    For previous generations, college was a decisive break from parental control; guidance and support needed to come from people of the same age and from within. In the past two decades, however, continued connection with and dependence on family, thanks to cell phones, email and social media, have increased significantly. Some parents go so far as to help with coursework. Instead of promoting the idea of college as a passage from the shelter of the family to autonomy and adult responsibility, universities have given in to the idea that they should provide the same environment as that of the home.

    To prepare for increased autonomy and responsibility, college needs to be a time of exploration and experimentation. This process involves "trying on" new ways of thinking about oneself both intellectually(在思维方面)and personally. While we should provide "safe spaces" within colleges, we must also make it safe to express opinions and challenge majority views. Intellectual growth and flexibility are fostered by strict debate and questioning.

    Learning to deal with the social world is equally important. Because a college community(群体) differs from the family, many students will struggle to find a sense of belonging. If students rely on administrators to regulate their social behavior and thinking pattern, they are not facing the challenge of finding an identity within a larger and complex community.

    Moreover, the tendency for universities to monitor and shape student behavior runs up against another characteristic of young adults: the response to being controlled by their elders. If acceptable social behavior is too strictly defined(规定) and controlled, the insensitive or aggressive behavior that administrators are seeking to minimize may actually be encouraged.

    It is not surprising that young people are likely to burst out, particularly when there are reasons to do so. Our generation once joined hands and stood firm at times of national emergency. What is lacking today is the conflict between adolescents' desire for autonomy and their understanding of an unsafe world. Therefore, there is the desire for their dorms to be replacement homes and not places to experience intellectual growth.

    Every college discussion about community values, social climate and behavior should include recognition of the developmental importance of student autonomy and self-regulation, of the necessary tension between safety and self-discovery.

    So often I hear people justify（为……辩解）their lack of family trips because their children are not old enough to remember them. This reason is so confusing to me. Who would travel based on another person's memory?

    Of course the kids aren't going to remember anything in infancy（婴儿期）, but you will. You will remember all the sweet memories you had with them.

    My parents would take me to Guatemala as a child. I don't remember a lot of the trip, but I do know that when I went back as a young adult, I felt comfortable in my surroundings. I didn't spend my time there discovering a new way of life. I spent the time having fun with my family. I love looking at pictures that we took together when I was my son's age. I don't remember them, but that's not the point. The point is, I was there with my family, and I know I was happy.

    Now that I'm a parent, I can't help but do the same. Last year, we took our 2-year-old son to Disney alongside his great-grandmother. His great-grandmother had recently begun to suffer from Alzheimer's. That trip was timed in the most magical way — right before my son was old enough to remember it and right before his great-grandmother began to forget. This makes me want to cry for them both. How did we get so lucky to have this moment to share with each other before big changes influenced our family forever?

    Realistically speaking, many families do not have the opportunity to travel internationally or visit pricey theme parks. I understand this more than you know, but I'm talking beyond that. They are young but these forgettable moments are still changing them. They will shape your child into who they will be tomorrow. The memories we absorb as their parents are also as influential as we have not finished learning our truths either.

Powerisers

    The ability to jump two meters in the air may not be something you have thought too much about. And most people have never considered running at 30 kilometers an hour. But just stop for a moment and think about how our new product could change your life.

    Your daily journey to your place of work is probably a mad dash for the bus. There is no point in taking your car because there are traffic jams, and anyway the car parks are probably very expensive or, worse still, full. Here is where Powerisers can help. It takes just a couple of minutes to put them on and then you are away, going past others or even jumping over the object which blocks your way.

    That is the practical use for our product, but then there is sport and exercise. Powerisers are set to be the next extreme sport and the deep-fit tools. You can imagine the 100 meters, the high jump or basketball performed by athletes wearing Powerisers. And what better way to build your muscles and keep fit?

    Our product is very simple. It is powered by a superlight spring, which uses the gravitational(重力的) pull from your body weight and pushes you with superhuman strength. There have been no records of serious injury related to the use of Powerisers, but extreme caution is recommended. We strongly advise the wearing of protective clothing, including at least a helmet(头盔).

    Powerisers make you feel as if you were walking on the moon. Now we make two different models: Basic and Professional. The Basic model is designed for the occasional users and costs around $ 500. The Professional model, which is designed for the competitive use, has a strongly-made structure and different springs, though that comes at the increased price of $800. Our Powerisers are guaranteed for two years and will be replaced without question if they fail during that period. That is how confident we are.

    "What kind of rubbish are you?" This question might normally cause anger, but in Shanghai it has brought about complaints over the past week. On July 1st, the city introduced strict trash-sorting regulations that are expected to be used as a model for our country. Residents must divide their waste into four separate kinds and put it into specific public bins. They must do so at scheduled times, when monitors are present to ensure compliance（服从）and to inquire into the nature of one's rubbish.

    Violators face the possibility of fines and worse. They could be hit with fines of up to 200 yuan ($29). For repeat violators, the city can add black marks to their credit records, making it harder for them to obtain bank loans or even buy train tickets.

    Shanghai authorities are responding to an obvious environmental problem. It generates 9 million tonnes of garbage a year, more than London's annual output and rising quickly. But like other cities in China, it lacks a recycling system. Instead, it has relied on trash pickers to sort out the waste, picking out whatever can be reused. This has limits. As people get wealthier, fewer of them want to do such dirty work. The waste, meanwhile, just keeps piling up. China produces 80 billion pairs of disposable(一次性的)chopsticks a year.

    Many residents appear to support the idea of recycling in general but are frustrated by the details. Rubbish must be divided according to whether it is food, recyclable, dry or hazardous(有害的), the differences among which can be confusing, though there are apps to help work it out. Some have complained about the rules surrounding food waste. They must put it straight in the required public bin, forcing them to tear open plastic bags and toss it by hand. Most upset are the short windows for throwing trash, typically a couple of hours, morning and evening. Along with the monitors at the bins, this means that people go at around the same time and can keep an eye on what is being thrown out; no one wants to look bad.
