M: I'm not wasting the holidays as you say. The computer is a good thing. On the Internet you can go to any part of the world; I can see everything in the world. It's more real than reality.
W: But... but you can't spend your entire summer watching that screen. You'll get a big bottom.
M: I'm not just watching the screen. I'm doing a lot of things—I'm sending e-mails, I'm learning things, I'm chatting in chat rooms...
W: Right! But I'll bet you're spending most of your time playing computer games—a time-wasting, mindless activity that'll turn your brain into Chinese doufoo.
M: No, it isn't a single mindless pastime. It's many activities: role-playing games, arcade games, adventure games, strategy games...
W: I understand the computer is a wonderful thing, but you have to be careful not to get too much of a good thing. Every life needs some variety in it. It would be a lot healthier if you played a chess game outdoors, in the park.
M: It wouldn't be the same. In those games in the park I can't play against the grandmaster of Moscow, can I？ And there are creative games in the computer, where I can learn city planning and psychology.
W: Well, what about me？ Don't you think I'd like a little attention？
M: Now, Baby, that's no way to talk. After all this time together, you know I love you.
W: I'm not so sure any more. It's time you made a choice. Is it going to be me or the computer？
M: Well...
