Tom and Daisy's Relationship

In The Great Gatsby, Nick goes to dinner at his cousin, Daisy's, house. He already knows Tom, but as he stays there longer he begins to learn things about him and Daisy's relationship. In the first chapter Nick makes Tom out to be a powerful, mean man. Nick says Tom has "two shining arrogant eyes" that had "established dominance over his face and gave him the appearance of always leaning aggressively forward." Tom and Daisy are basically described by Nick as complete opposites, as Tom is the aggressive man and Daisy appears to be the quiet woman that is very innocent. During the dinner there are a couple moments that show there are problems between Daisy and Tom. There is the obvious fact that Tom has a woman in New York, but there are also smaller things like when Tom asks Nick what he does for a living. Nick says he is a bond man and he will know about it if he stays in the East. The Tom responds back, "Oh, I'll stay in the East, don't you worry, I'd be a God damned fool to live anywhere else." and after he says this he looks at Daisy, then back at Nick "as if he were alert for something more." I believe these issues between Tom and Daisy could be an important issue and I believe that the fact that they are almost polar opposites could lead to more issues between them later on in the book.
