My friend Li Wei looks shy and childish, but in fact she is outgoing and bravely. She has many friends. Some are of her ages and some are very much older. She even makes friends in strangers. Last year, where we met two American tourists on a bus, she started to practice speak English with them. Now they have become pen pals. With their friends she talks about hobbies, childhood stories and something that interests them. Li Wei is quite active in class. She wants answer all the teachers' questions. Sometimes she tried to correct their mistakes, too!
