The Enormous Radio

I think everyone can find something for them in this opus (1). In my opinion, the author wanted to say that [some people live by other's lives trying to hide their own problems] (2). However, the little radio disturbed (3) enormous (4) happiness of Jim and Irene (5) which just seemed right and loving each other. Why did J. Cheever choose a (6) radio? I consider the answer (7) is that the radio is a modern invention, reflecting pproblems (8) of modern life such as separate family (9) that may seem "happy".

Notes

1. An opus is a great work of art, world-renowned.  Does this apply to the source?   I think not.  Just use "book" or "novel".

2. "Live by another's life" doesn't make sense.  You can say, "Some people live their lives by trying to hide their own probems."

3. We don't say "disturb happiness".  Use "ruined Jim and Irene's happiness".

4. We don't say "enormous happiness".  Delete "enormous".

5. ...happiness, which seemed ideal.

6. Are you asking why he chose a radio vs. something else (e.g., a dog)?  Or are you asking why he chose THIS radio vs. a different radio?

7. We consider something TO BE something.  => ...answer to be that the radio...

8. => "the problems of modern life" (need "the" to refer to specific problems, those of modern life)

9. "separate family" doesn't make sense.  What arre you trying to say?
