The Great Gatsby One

Nick is detached because he doesn't really know the people and town that well. It seems as if he feels more like he is watching everything rather than participating in it.

Gatsby on the other hand seems like he is in his own world. He doesn't deal with people like Tom or Myrtle, he deals with criminals and strange people like Owl Eyes. He seems a bit Warhol-ish that way.

Nick doesn't seem like he wants to get involved with either Tom or Gatsby. He seems like he wants to get into bonds and focus on nothing else. He hasn't tried to get involved with Tom or Gatsby, they just show up and take advantage of his unwillingness to say no. He seems detached because of this unwillingness to meet with his neighbors.

Gatsby seems detached because he gets involved with people, but he's awkward around them. He messes up details about his own life, such as where he grew up and what happened to his family. He seems like he is in a constant daze in that way.
