This is pretty sophomoric stuff (from the linked advertisement for the book the author is writing about): > "We evolved from tribes to larger communities where meeting strangers had the potential to grant us access to food and other resources. Unknown people were treated as guests and were offered generous hospitality for this reason." I'm pretty sure that the vast majority of isolated communities would react to an influx of strangers with a mixture of surprise, interest and alarm. Most probably this would be alleviated by some kind of formal meet-and-greet (at a dinner, say). Randomly accosting people on the street or at a place of business in an attempt to engage them in conversation is not the way to go about it, the vast majority of people will interpret this as rude or bizarre behavior. Instead look into various clubs, volunteer organizations, etc. where the very fact that you've put in the effort to show up will encourage other people that talking to you might be a worthwhile pursuit.
