How do you explain the bond between man and wife? Well, for one thing, it’s private. What people do in their own marriage is their own business.

In this remark, Gibb frames marital “bond” less as a publicly legible ideal and more as a protected sphere of intimacy. The emphasis on privacy suggests that the durability or meaning of a marriage cannot be fully explained—or judged—by outsiders because its defining features are lived in private: habits, compromises, loyalties, and shared history. The second sentence pushes back against social scrutiny and moralizing, implying that external commentary often misunderstands what sustains a relationship. As a statement, it also functions defensively: it asserts boundaries and autonomy, treating marriage as a domain where consent and mutual understanding matter more than public opinion.
