(二) Have you heard about teleworking? It means working from a distance, in other words, not working in an office but working at home. You use the computer and the Internet to keep in touch with your boss, but instead of being tired of an office work, you can work in your own comfortable room. The idea sounds nice, doesn't it? You can do all your research on the World Wide Web and send in all your work by e-mail. Well, that's exactly what my boss said to me two years ago. "Jenny, how would you like to work at home?" he said. At first everything was great. My job was editing articles for a university, and so I spent most of my time sitting in front of a monitor and typing busily at the keyboard. Through the Internet I had access to all the information I could possibly want. It was really good being at home, too. I didn't have to waste any time traveling, and I could stop and make myself a cup of coffee or a sandwich if I wanted to — I was quite free and happy. But then things started to change. I put on weight, because I wasn't going out as much as I had before. I stopped wearing smart dresses, because a jogging suit ( 慢跑衣 ) and trainers were so much more comfortable. My friends stopped telephoning because I didn't meet them on the bus or in the cafe. I knew something had to change. I needed to get back out into the world. So I telephoned my boss, "Please let me come back to the office — I'm going mad on my own!" And then goodness, he did. If you want my personal opinion, teleworking may become popular in the future... but not for me!
