When I was about 12 1 had an enemy, a girl who liked to point out my shortcomings．Week by week her list grew: I was skinny, I wasn't a good student, I was boyish, I talked too loud, and so on．I put up with her as long as I could．At last, with great anger, I ran to my father in tears．
He listened to my outburst quietly．Then he asked, "Are the things she says true or not?"
True? I wanted to know how to strike back．What did truth have to do with it?
"Mary, didn't you ever wonder what you are really like? Well, you now have that girl's opinion．Go and make a list of everything she said and mark the points that are true．Pay no attention to the other things she said．"
I did as he directed and discovered to my surprise that about half the things were true．Some of them I couldn't change (like being skinny), but a good number I could and suddenly wanted to change．
For the first time in my life I got a fairly clear picture of myself．
I brought the list back to Daddy．He refused to take it．
"That's just for you," he said．"You know better than anybody else the truth about yourself, once you hear it．But you've got to learn to listen, not to close your ears in anger or hurt．When something said about you is true you'll know it．You'll find that it will echo inside you．"
Daddy's advice has returned to me at many important moments．

The year 2000 will bring big changes in communication．Cell phones will be small enough to carry in your pocket．Videophones will let you see the person you are talking to on the phone．Tiny hand size computers will know your favorite subjects．The Internet and email will be everywhere．Technologists believe 2000 will be the year of video messaging．You will be able to see whom you're talking to．
Also in the near future small wireless boxes will pick up information from satellites．In 5 years, computers won't need to be connected through wires．
All of this will be good for rural areas and countries that don't have cable or telephone now．

Constance Hale is the author of Sin and Syntax, "I believe that email has been an incredible boon to communication．People are writing today where they would have been telephoning yesterday．So people are engaging with words more than they have for the last couple generations．"
If people use email and the Internet more, it could make people better readers and writers．Some people think the most important part of communication is to make people understand each other better．Will technology make that easier?

Bob Parks is an Associate Editor of Wired Magazine, "Bob's morning begins at about 6:45 am．and Bob is kind of mad, because Bob usually gets up at around 7:15 and likes to cut it close with his morning commute, but I look at my radio and it says that there's a traffic jam on 101 South and I'm gonna need an extra 1/2 hour．And so my radio has got a net connection, wireless net connection as well as a good old power cord to the wall and it has received notice that there's a traffic jam and it has calculated an extra 1/2 hour commute time．"
Some day everything may be connected to the Internet．Your refrigerator will add milk to your Internet grocery list when the date on the carton has passed．Light bulbs will be ordered before they burn out．
