I was only nine years old when I learnt how to use a computer. My mother is my first teacher. I know how to type and how to visit a web site on the Internet. One day, mum was not at home. I turned on the computer and began to learn how to chat on net. The first one I met there was a boy called Tom. He greeted me politely. When he knew that I was only a 9-year-old girl and almost knew nothing about chatting on net, he started showing me how to use the chatting tools, how to download, and how to send e-mails. I learnt a lot from him.
