    "abstract": "We investigate a relationship network of humans located in a metric space\nwhere relationships are drawn according to a distance-dependent probability\ndensity. The obtained spatial graph allows us to calculate the average\nseparation of people in a very simple manner. The acquired results agree with\nthe well-known presence of the small-world phenomenon in human relationships.\nThey indicate that this feature can be understood merely as a consequence of\nthe probability composition. We also examine how this phenomenon evolves with\nthe development of human society.",
