The fact that men have a same origin and live in the same universe means that they are representatives of a same unity. Deep down, they are also related (or connected) among them; that they consider (or not) themselves as strangers, this just depends on the feeling (or sensation) that dictate their relationships. In their country, two fellow coutrymen whose paths berely cross (or see each only only briefly) with inferrence, would effusively rush themselves up (or throw themselves) into each other arms if they would happen to meet in a desert, among Cannibles.
