It is invariably saddening to look through new eyes at things upon which you have expended your own powers of adjustment.

F. Scott Fitzgerald

Great Gatsby, Chapter 6. Nick at Gatsby’s party feels an unpleasantness in the air and believes that he is looking at West Egg and the party through new eyes, Daisy’s eyes. He is saddened by what he sees as that society’s isolation and superficiality.
