Prior to the development of the smartphone, the queue or line-up as it’s known in North America used to be one of the few places where it was deemed socially acceptable to talk to strangers. These days however the majority of people appear too absorbed by their iPhones to strike up a conversation. Airlines are on the verge of allowing such devices to be used on flights; no need to talk to the person sitting next to you. And even National Parks are setting up Wifi networks. We have never before been so connected to, and yet disconnected from the world around us.
