It was David, who was looking down at his feet nervously. David had lived together with his mother and grandfather since he lost his father. But when he turned 13, his grandfather died and his mother was killed in a car accident. He became very 37, refusing to talk to others from then on. The first two times we met, I did most of the 38 , but David didn't say a word. He just sat in the chair and was even careful not to allow our eyes to meet. When he was going to 39 after the second visit, I put my hand on his shoulder. He accepted it, but still didn't 40 me. When he came the next week, I suggested playing a game of chess. He agreed. After that we played chess every Wednesday afternoon - in complete silence. It was not 41 to cheat in chess, but I managed to let him win once or twice. But why did he 42 look at me? "Perhaps he only needs someone to 43 his pain with," I thought. I kept wondering and playing with him, until some months later, suddenly, he looked up at me, "It's your turn," he said. That made me 44 because I could see the hope of success. After that day, David started talking. Soon he got a lot of 45 in school and joined a bicycle club. He wrote to me several letters about how he would try to get into university. After some time, the letters 46 . I knew he had really started to live his own life. Maybe I gave David something. At least I learned a lot from him. He 47 me how one – without any words – can reach out to another person. All it 48 is a shoulder to cry on, a friendly touch and an ear that listens. 37.

    "Hey, Tahlia! How's the model?"
    I had just taken a bite of my hot dog __21__ I heard a familiar voice yelling at me from across the crowded school yard. I saw a group of popular girls who were all __22__.
    "What kind of __23_ are you going to do? An ad for a Frankenstein movie?" More laughter. My stomach twisted into a tight knot. How could they humiliate (羞辱) me like this, __24__ the entire school? As I walked into the cafeteria, I __25__ the dark scars on my right hand.
    At 9 months old, I knocked over a tea pot and dumped boiling water allover my hands and stomach. My parents __26__ me to the hospital, but I had to have skin graft (移植) operation. I was in so much pain! But what __27__ me most were the cruel things people said about how I looked, __28__ that day at lunch.
    The girls were being supermean to me because they'd heard I was considering doing some modeling. A close friend had suggested that I shouldn't let my scars limit me and that I might __29__ a good model.
    But after that __30__ at school, I was sure I'd made a huge mistake. Upon arriving home, I covered the mirror with a blanket, fell on my bed and sobbed.
    The next day, I __31__ myself to go to school. At lunch my best friend Jesse tried to encourage me: "You can't __32_ forever, Tahlia. So what if you have a few scars? Just go outside and show them that you're just as good as they are." Although I knew he was right, I couldn’t __33__ standing up for myself like that.
    However, that night as I sat on the bed, my friend's words replayed in my mind. I'm __34__ hiding from myself, I thought. How stupid! Slowly, I stood up, walked over to the __35__, and tossed the blanket aside. There, in the mirror I saw a slim, dark-haired, blue-eyed girl, looking just fine, __36__ with a few scars.
    The next day I wore a comfortable T-shirt to school. What's more, I had lunch outside the cafeteria, __37__ beside those mean girls. They were shocked that I should dare to walk into their territory. I felt __38_ too—free and happy.
    Sometimes people still look at me strangely. They __39_ and stare, but I don't let it get to me. I have applied to several modeling companies, and at least one company is considering me for jobs. Maybe I'll never __40_ posing on the runway, but I do know one thing: I'm done.
