What is Mr Kapasi's view of the Das family in Interpreter of Maladies?

Mr. Kapasi views the Das family with both fascination and frustration. He is drawn to Mrs. Das and develops an emotional connection to her as they share personal stories, but he also feels disappointed by the family's disinterest in his role as a tour guide and interpreter. He often sees them as representative of the unfulfilled desires and lack of communication that he perceives in his own life.
