How does Gatsby's failure represent personal failure? What are Gatsby's gestures and social mistakes? How does the weather reflect Gatsby's...

Gatsby's life failure is that he can't get what he wants,
although he went to great lengths to get it and by many people's standards he is likely
thought of as successful. After all, he's filthy rich. He failed because you can't do
anything with your money if you are dead, and you certainly can't participate in the one
thing you worked so hard for, a relationship with
Daisy.

During the scene in chapter 5 before Daisy and
Gatsby got together, it was raining. Then, after their relationship seems repaired, the
sun is shining. In the end, on the day of the funeral, when all hope gone, it rains
again. Rain often represents failure, depression, or even evil. When Gatsby's dream was
achieved, the weather was good.

Gatsby wants Daisy to say
that she loves him, and that she never loved Tom, or if she did love him even for a
moment, he wants to know that she loved Gatsby more.
