She likes going to school, but there are some things she doesn’t like, such as PE. She enjoys playing sports. She thinks sports are interesting and exciting. But she doesn’t like doing physical exercises in PE classes. She feels that they are boring! Her favourite subject is Science. It seems that the amazing and useful Science attracts her. She thinks she is on the way to be a scientist. She wishes to invent things to make the world more and more beautiful. In her free time, she often goes to the beach. She loves just sitting around and talking to friends there. She’s getting better at understanding boys, but she hates listening to hours of talk about football. “It’s not interesting at all!” she once said to me. That is my penfriend Alice.
