Seventy years ago, a group of well-known people from the art world headed by an Austrian conductor decided to hold an international festival of music, dance and theater in Edinburgh. The idea was to reunite Europe after the Second World War.

    It quickly attracted famous names such as Alec Guinness, Richard Burton, Dame Margot Fonteyn and Marlene Dietrich as well as the big symphony orchestras (交响乐团). It became a fixed event every August and now attracts 400,000 people yearly.

    At the same time, the “Fringe” appeared as a challenge to the official festival. Eight theater groups turned up uninvited in 1947, in the belief that everyone should have the right to perform, and they did so in a public house disused for years.

    Soon, groups of students firstly from Edinburgh University, and later from the universities of Oxford and Cambridge, Durham and Birmingham were making the journey to the Scottish capital each summer to perform theater by little-known writers of plays in small church halls to the people of Edinburgh.

    Today the “Fringe”, once less recognized, has far outgrown the festival with around 1,500 performances of theater, music and dance on every one of the 21 days it lasts. And yet as early as 1959, with only 19 theater groups performing, some said it was getting too big.

    A paid administrator was first employed only in 1971, and today there are eight administrators working all year round and the number rises to 150 during August itself. In 2004 there were 200 places housing 1,695 shows by over 600 different groups from 50 different countries. More than 1.25 million tickets were sold.

    A few years ago, I took a sightseeing trip to Washington, DC. I saw many of our nation's treasures, and I also saw a lot of citizens on the street—unfortunate ones, like beggars and homeless folks.

    Standing outside the Ronald Reagan Center, I heard a voice ask. “Can you help me?” When I turned around, I saw an old blind woman with her hand extended. In a natural reflex (自然反射), I reached into my pocket, pulled out all of my loose change and placed it in her hand without even looking at her. I hated being disturbed by a beggar.

But the blind woman smiled and said: “I don't want your money. I just need help finding the post office.” In an instant, I realized what I had done. I had acted with prejudice (偏见)—I had judged another person simply for what I thought she had to be.

    I hated what I saw in myself. This incident brought back my central belief. It reminded me that I believed in being humble (卑下的), even though I'd lost that belief for a moment.

    The thing I had forgotten about myself is that I am an immigrant (移民). I left Honduras and arrived in the US at the age of 15. I started my new life with two suitcases, my brother, my sister and a strong mother. Through the years, I have been a dish washer, roofer, mechanic, cashier and pizza delivery driver, among many other humble jobs. Eventually, I became a network engineer.

In my own life, I have experienced many acts of prejudice. I remember a time at age 17—I was busboy (餐馆工), and I heard a father tell his little boy that if he did not do well in school, he would end up like me. I have also seen the same treatment of family and friends, so I know what it's like, and I should have known better.

    But now, living my American middle-class lifestyle, it is too easy to forget my past, to forget who I am and where I have been, and to lose sight of where I want to go. The blind woman cured me of my blindness. She reminded me of my belief in being humble, and to always keep my eyes and heart open.

    By the way, I helped that lady to the post office. And in writing this essay, I hope to thank her for the priceless lesson she gave me.

    Attention from strangers is nothing new to me. Questions about my height is the center of almost every public interaction. My friends say my height is just a physical quality and not a personality aspect. However, when I reflect on my life, I realize that, my height has shaped my character in many ways and has helped to make me who I am.

    I learned how to be kind. When I was younger, some parents in my neighborhood regarded me kind of dangerous because I was so much larger than other children my age. I had to be extra welcoming and gentle simply to play with other children. Of course, now my coaches wish I weren't quite so kind on the basketball court.

    I learned the quality of not being too proud about myself. At 7 feet tall, everyone expects me to be an amazing basketball player. They come expecting to see Dirk Nowitzki, and instead they might see a performance more like Will Ferrell(successfully starred a professional basketball player). I have learned to be modest and to work even harder than my fellows to meet their (and my) expectations.

    I developed a sense of lightheartedness. When people playfully make fun of my height, 1laugh at myself too. On my first day of high school, a girl dropped her books in a busy hallway. I got down to her level and gathered some of her notebooks. As we both stood up, her eyes widened as I kept rising over her. Astonished, she dropped her books again. Embarrassed, we both laughed and picked up the books a second time.

    All of these lessons have defined me. Looking back, I realize that through years of such experiences, I have become a confident, expressive person. Being a 7-footer is both a blessing and a curse, but in the end, accepting who you are is the first step to happiness.

    Natural selection is the process by which one type of animal within a species thrives because of certain characteristics that make it more likely to live than others in its group. The history of the peppered moth（灰蛾）is an example of the natural selection process.

    In 19th century England, certain types of peppered moths were able to better blend（融合）into their surroundings. During that time period, great changes were happening in Great Britain. The Industrial Revolution was part of this change, and with it came air pollution. Natural selection often takes hundred or even thousands of years to occur. For the peppered moth, this process occurred comparatively quickly.

    At the beginning of the Industrial Age, most peppered moths in England were light-colored and covered with black markings, although a few moths had dark-colored wings. Because the light-colored moths blended into the light-colored bark on the trees, they could not be easily seen by birds that would eat them. As the air grew more polluted, however, tree trunks became covered with soot（烟煤）and became darker. The light-colored moths became easy for birds to see against the dark tree trunks. Since the dark-colored moths now had the advantage, their numbers grew. Within 50 years, the peppered moth went from being mostly light-colored to being mostly dark-colored.

    In the 20th century, the air cleared up, and the peppered moth population changed again. As tree trunks lighted due to less soot in the air, light-colored moths once again had an advantage. Their numbers increased as soot levels declined. Depending on their environment, the coloration of the moths helped them to be “naturally selected” to survive.

    “There's a mother in PICU (儿童重症监护病房) who wants to talk about a kit she received.” the nurse told me. “Something about it made her cry.”

    I've been a child-life specialist at the Cleveland Clinic Children's Hospital since 2000. I help families understand diagnoses and treatment plans and manage the ups and downs that come with caring for a sick child. Tough talks with parents are part of the job, it still makes me feel nervous.

    The kits the nurse was talking about were something I had recently introduced to the hospital: Comfort Kits from Guideposts. They were supposed to make a child's experience here easier, not upsetting.

    When I came across the kits at a conference, I fell in love with them. A treasure box of items designed not only to entertain kids, but to comfort and inspire them. There's a coloring book, a stress ball, a CD of relaxing music, a hairy star named Sparkle, a journal and much more. I really believed these kits would help kids. I wished I hadn't been mistaken.

    At the patient's room in PICU I saw a little girl, sleeping soundly, surrounded by tubes and machines. My eyes met her mother's. The kit was open on her lap and tears were running down her cheeks.

    “I'm Shannon. I manage the Child Life Department.” I said. “I'm sorry if the kit upset you. It's a new item…”

    The mother shook her head. “This has been one of the worst days of my life. I felt so scared and alone. Then I was handed this box. I know it's for my daughter, but it's just the comfort I needed. I wanted to say thank you.”

    With that I knew Comfort Kits belonged here. We've been using them for almost three years now. Each child who's admitted to the hospital receives one. Every day I see kids coloring, journaling, playing with Sparkle.

    But as this mom showed me Comfort Kits aren't just for kids. The hope they bring, which can be in short supply in hospitals sometimes, is felt by the whole family.
