These days my son has turned his computer into an electronic playground. He plays football, rides horses, drives racing cars, and does a whole bunch of other things on the computer. The funny thing about it is that, no matter what he plays, he always wins first place. I wonder if he'll be able to cope with a defeat in real life.
Don't worry. He'll cross that bridge when he comes to it. My son reads a lot on his computer and uses e-mail to send messages to his friends almost every day. He's really absorbed by the discussions.
That's exactly like my wife. She spends at least two hours a day on the computers discussing things ranging from stock prices to soft-ware standards.
I guess using a computer has a great deal to do with human interaction. Getting in touch with each other must be more fun to your wife and my son than the coolest computer games or the hottest information.
