The first time I saw Carlos I would never have believed he was going to change my life.I had my arms full of books and I was rushing into the classroom when 1 ran into something solid. It was Carlos.

"My... you're tall," he said. The whole class burst out laughing .

“Take that seat,” Mr. McCarthy told the cocky(骄傲自大的) newcomer Carlos,pointing to the only empty one , in the back of the room.

Carlos laughed widely. "But I need a couple of dictionaries."

The bell rang for classes. As I stood up to go, I saw Carlos coming toward me. "I'm sorry I embarrassed you," he said . I looked straight ahead over the top of his black hair. "That's all right."

"I ought to know better." He was still blocking my way. "What's your name?" "Karen Forbes." He held out his hand. Unwillingly, I shook hands with him. He looked up at me seriously with his brown eyes. " I am Carlos . I don't see why you're so touchy."

It was the school elections that made me think of Carlos again. Carlos was voted vice-president.“How come ?”I kept asking myself, "How come this shrimp(虾)who’s only been in town for a little over a month gets to be so popular?"

So on that morning,I stopped Carlos and said,“It doesn't seem to bother you — being short.” He looked up at me, "Of course I mind being short.But there isn’t anything I can do about it. When I realized I was going to have to spend my life in this undersized skin, I just decided to make the best of it and concentrate on being myself." "You seem to get along great,” I admitted, "But what about me? The trouble with you is you’re afraid to be yourself. You’re smart. And you could be pretty. In fact, you might be more than pretty.” I felt myself turning red…
