my 15 years old spend too much of his time on the computer, chatting with friends, playing online computer games, and playing his guitar. all this is done in the garage that we have converted to a rumpus room. we don't see much of him except when he comes into the kitchen to get his snacks. this is so worrying because he is becoming such a home body, he has alot of friends, but they all seem to be the same just chatting on the net, or playing games on the net.
