remember it really well My parents drove me to the school and said goodbye to me. I (A) walked into the I school I didn't know what to feel I was excited and scared and a bit nervous, all (B). There were lots of other kids around. They were already in groups of friends, but none of them said hello or anything It was a strange feeling for me, like I didn't really belong there. I wanted to be somewhere else, (C). The first thing I had to do was register, so l went to a room in the school that hada sign saying Administration Suddenly. I felt like I was some kind of criminal. They started asking me (D) questions. Then I wvent off to my first class My first class. Wow, that was horrible. Perhaps it was because my hair or clothes were different, but everyone just looked at me in such a strange way. And just like when I arrived, no one came to talk to me. Incredibly, that's never happened: no one has ever taken the time to (E) or like me. I have friends because I made the first move to meet people. Maybe the worst class that day, though, was Science. The teacher wasn't too bad She introduced me (F) and showed me where to sit. But the other students? Well, they looked at me like I was a guinea pig or something they were going to use for an experiment. I hated every minute Then there was a break and I went to sit somewhere alone. (G). But I thought they'd want me to keep trying, so I tried to be more positive in the next class. Not so good, though Everyone talked to other students, (H). At the end of the day, I couldn't wait to get out of there. But, as time passed, things have got better. Now I'm doing fine and I get OK grades. I've learned lots of things -but not what the teachers teach I've learned that I'm strong and brave. I've learned that I will succeed even if some things aren't the way I wantthem to be
