Allow me to introduce you to: an abstract concept of facebook-
People, separated by thousands of miles, tap messages into their glass topped smart rocks that can then be seen by other people with smart rocks - it does this communicating with big metal trees that talk to magic caves, where millions of smart rocks think about those messages and pass them over to other magic caves by a glass wire, which in turn pass the messages to another metal tree and over to other glass topped smart rocks for people to read.
You're fine :)
It's just weird to me I guess, someone in my age group who doesn't know the CNC games.
