Perhaps you envy me for being able to work from home on the computer. I agree that the Internet has made my job a lot easier. I can write, submit and edit articles via email, chat with my colleagues on line and discuss work with my boss. With a click of the mouse, I can get all the data I need and keep up with the latest news. But then, communicating through the Net can be frustrating at times. The system
may crash. Worse still, without the emotional cues of face-to-face communication, the typed words sometimes seem difficult to interpret.
