Personal computers and the Internet givepeople new choices about how to spend their time.Somemay use this freedom to share less time with certain friends or family members,but new technology will also let them stay in closer touchwith those they caremost about. I know this from personal experience.E-mailmakes it easy to work at home, which is where I now spend most weekends andevenings. My working hours aren' t necessarily muchshorter than they once were,but I spend fewer them at the office. This lets me share more time with myyoung daughter than I might have if she' dbeen born before electronic mailbecame such a practical tool.TheInternet also makes it easy to share thoughts with a group of friends. Say youdo something fun一see a greatmovie, perhaps一andthereare four or five friends who might want to hear about it. If you call each one,you may tire of tlling the story.Withe-mail, you just write one note about your experience, at your convenience, andaddress it to all the friends you think might be interested.They can read yourmessage when they have time, and read only as much as they want to. They canreply at their convenience, and you can readwhat they have to say at your convenience.E-mailis also an inexpensive way to stay in close touch with people who live faraway. More than a few parents use e-mail to keep in touch,even daily touch,with their children off at college.Wejust have to keep touch in mind that computers and the Internet offer anotherway of staying in touch. They don' t eliminate any of the oldways.
