In Vladimir Nabokov's "Ada, or Ardor: A Family Chronicle," the character Marina expresses a sentiment about the close bond between two individuals, viewing them as if they were siblings. This perspective reflects a common misunderstanding among people who think that closeness or familiarity can override the complexities of relationships. Marina's assertion simplifies their connection, implying a different reality that may not truly represent their feelings or circumstances.

This moment highlights a broader theme in the novel regarding the nature of relationships and the ways individuals perceive and justify their emotions. By suggesting that familiarity renders the truth less significant, Nabokov explores how societal norms and personal beliefs may distort reality, turning profound emotional truths into mere clichés or oversimplified statements.
