Here's a breakdown:
Tom Buchanan:
* Initial Impression: Nick sees Tom as a wealthy, arrogant, and domineering man, someone who embodies the "old money" world that Nick is trying to understand. He is initially drawn to Tom's confidence and sense of belonging, but quickly recognizes his flaws.
* Conflict: Nick is uncomfortable with Tom's blatant affairs, his hypocrisy, and his treatment of Daisy. He witnesses Tom's cruelty firsthand and sees his casual racism and sexism. Nick is also aware of Tom's jealousy of Gatsby and his attempts to sabotage Gatsby's relationship with Daisy.
* Disillusionment: As the story progresses, Nick's respect for Tom further diminishes. He ultimately sees Tom as a shallow and destructive figure who is ultimately responsible for the tragic events that unfold.
Daisy Buchanan:
* Attraction: Nick is initially attracted to Daisy's beauty and charm, but he recognizes her shallowness and her need for wealth and social status. He sees her as a beautiful but ultimately empty vessel.
* Sympathy: Nick feels a sense of sympathy for Daisy, recognizing her trapped situation in a loveless marriage and her longing for a more fulfilling life. He senses a genuine emotional connection between her and Gatsby, even if it's ultimately doomed.
* Disappointment: As Nick witnesses Daisy's indecision and her ultimate choice to stay with Tom, he feels a sense of disappointment and disillusionment. He sees her as weak and ultimately incapable of making difficult choices.
Overall, Nick's relationship with the Buchanans is characterized by a mix of admiration, disgust, and ultimately, a deep sense of disillusionment. He represents the outsider looking in, trying to understand the allure of the "American Dream" and the hollowness of the upper class life, as embodied by the Buchanans. He is ultimately alienated from them, recognizing the flaws in their lifestyle and the destructive nature of their pursuit of wealth and status.
