Final answer:
Gatsby stops watching over Daisy's house in 'The Great Gatsby' because he realizes his dream and past illusions about Daisy are lost, encapsulating a deep sense of disillusionment.
Step-by-step explanation:
The excerpts provided are from various literary works that all deal with themes of loss, love, and the complexities of human relationships. In F. Scott Fitzgerald's 'The Great Gatsby', Gatsby stops watching over Daisy's house because his romantic dream has been shattered; he recognizes that the past cannot be recaptured and his illusions about Daisy are irrevocably lost. This moment of realization is a turning point for Gatsby, highlighting a profound sense of disillusionment and the ephemerality of his idealized love.
This notion is mirrored in different ways across the other excerpts, whether it's Judy's tears in a Fitzgerald short story, the Hadleys' reliance on technology supplanting real experiences in Ray Bradbury's 'The Veldt', or the social ostracism and romantic misunderstandings in Henry James' 'Daisy Miller'. Each passage explores the theme of an irrevocable loss of innocence, beauty, or love as well as the impact of societal norms and personal disillusionment on the characters.
