N is obsessed with Animal Jam, an online game set in a world called Jamaa. You pick an animal avatar, explore different eco-zones, and play games, swap virtual stuff & chat to fellow players. It's pretty safe and harmless, and is somehow linked to National Geographic.
Millions of people play it all over the world. N plays it with her Argentinian friend Martina in Beijing. Every now & again she gets a Skype message and after a brief chat one of them says "Do you wanna play AJ?" And off they go, chatting & playing at the same time.
It's a far cry from playing marbles or cowboys & indians in the back garden.
