Last night when I walked home from the restaurant with wifi, (the restaurant had a wifi Internet connection, that is; not that I was walking home with someone called Wifi) I passed an Internet place. One of those places that every town has; with a few rows of PCs, each separated by a piece of wood to afford some sort of privacy. Along the back wall were eight computers. Seven of them were occupied by teenage boys wearing headphones and all creeping around the same landscape – it looked like a castle or something – and shooting at each other. At the end of the row, there was a smaller boy. He was playing Space Invaders.
