Answer: Nick and Gatsby have different points of view regarding whether or not the past can be repeated.
Step-by-step explanation:
The Great Gatsby, a novel written by F. Scott Fitzgerald, is about a man called Jay Gatsby, who desperately tries to get his ex girlfriend's attention.
Gatsby thus throws parties every night, attended by hundreds of people, hoping that Daisy would show up, or at least that she would notice him. He spends his time staring at the green light by the house where Daisy, his former lover, lives. The problem is that Daisy is a married woman now, and has a child. It is obvious that their relationship cannot go back to what it was. This is what Nick, Gatsby's neighbor and the narrator of the story, suggests. Nick arranges for the two of them to meet in his house, and really tries to help Gatsby. When, however, Nick sees that nothing that Gatsby does will ever be enough for Daisy to love him again, he says to Gatsby: "You can't repeat the past."
Gatsby replies: "Can't repeat the past? Why of course you can!"
Nick is a realist in this case, while Gatsby's unconditional love makes him unrealistic.
