connections?
character development, conflicts, themes, motifs, settings
In all three of the books we have read so far, the character development has been much the same. Salinger never comes out and says who each of the characters are, or how they connect, rather he creates a spiderweb of relations, not just within a single book, but throughout all 3. We learn about the individuals slowly and gradually, and their importance to the story is never apparent in many cases until one reflects back after reading.
All of the conflicts in each book, are always the same as well. The peak of suspense is never in the book itself, rather it is something that happens outside the realm of the book. In banana fish, it was how Seymour was sent to war and lost himself, in Uncle wiggly, it is the lack of love and respect elouise is given, in Eskimos, it is the mystery of the brother, and the accepting of the angry girl. None of the conflict was ever in any form of action, but it was always on a more mental and reflexive level. 

The themes in all the books so far have been somewhat relating to color, and the conflict of the good and evil in life. Clearly Yellow is innocence and Blue is evil, and greed, but what the books have been about is the transition the characters take between the two. Seymour transitions during war, Elouise through a life of disappointment, and the young girl finds it through seeing the misfortune of others. The themes are rather consistent in each of the short stories.
the settings of each of the books have been around the same time period. just after world war 2, the stories often include veterans and how they deal with their emotion. The setting in place often varies, but emotional setting, the mind sets of the characters are usually the same. they are dangerously self aware of what they are, and how they fit into society, and in many of their cases thats the worst thing for them.
