Final answer:
The relationship between two people based on shared interests in the absence of familial ties or geographical closeness is characteristic of an individualistic society.
Step-by-step explanation:
Two people becoming friends based on the same interests and similar personalities, without taking into account their relationships by blood or geographical proximity, is characteristic of an individualistic society. In individualistic societies, personal achievements and individual rights are emphasized, and relationships are often formed based on personal preferences and similar interests.
This contrasts with collectivist societies where individuals might prioritize group goals and relationships based on social roles and obligations.
