"Everybody uses mobiles. They use them all the time, just constantly. It's a phenomenon of the modern age. Everybody's talk, talk, talking, all the time, little black telephones pressed up to their faces. Where does all that conversation come from? What happened to all that conversation before mobiles were invented? Was it all bottled up? Burning ulcers in people's guts? Or did it just develop spontaneously because technology made it possible?" - Lee Child.
