Strangers are friends that you have yet to meet.

The aphorism reframes “strangers” not as threats or outsiders but as relationships in an early, unrealized stage. By treating unfamiliar people as potential friends-in-waiting, it encourages openness, curiosity, and a presumption of goodwill—an ethical stance that can reduce social anxiety and prejudice. The line also implies that friendship is often contingent on opportunity and contact rather than deep prior compatibility: many bonds exist only because circumstances allow people to meet. As a piece of social wisdom, it functions as an invitation to hospitality and conversation, suggesting that community is built by converting anonymity into recognition.
