Everyone starts off as a stranger
I'm required to talk to thousands of strangers face to face for work. And I've met some pretty incredible/unforgettable people along the way.
For example when I was in the Western Sahara 2 months ago, a family invited me in for dinner and 3 cups of tea while I was waiting outside for a car repair. Word of mouth spread and over a dozen family/friends/neighbors came over to see the strange visitor.
The family made this massive dinner for me which consisted of this huge communal bowl of rice and random meat. No silverware, just using fingers like shovels. It was like something out of Raiders of the Lost Ark.
So yeah, no stranger danger for me. I even signed up for Couchsurfing a few years ago. Has anyone ever used it? It's pretty cool.
