"Think about how many people you pass on a daily basis. In most cases, it’s a pretty hefty number, a fact which might make the next question just a teensy bit more depressing: how many of those people do you strike up a conversation with? Odds are the number just dwindled dramatically. You can’t be expected to develop a life-long friendship with every face in the crowd, sure, but the difference does raise a few questions about what exactly we’re doing with our daily routines."http://www.vagabondish.com/talk-to-strangers-travel-advice/
