Passage from FASTING, FEASTING

The passage is taken from Fasting, Feasting, a novel published in 1999 by Indian novelist Anita Desai.  In the excerpt, Arun, an exchange student from India, joins members of his American host family for an afternoon at the beach.  Read the passage carefully and analyze how the author uses such literary devices as speech and point of view to characterize Arun's experience.
