Extremely Loud and Incredibly Close 2nd

The story is still really sad, yet, like Dusty said in class, the boy's journey brings a sense of closure to himself, as well as the many people he meets on his journey.  The obvious symbol is from the digging up the Dad's grave.  Another note I found interesting is how Oskar mentions you should go to a psychologist if you aren't sad when your father dies.  Yet, in several instances, Oskar holds his emotions in.  This idea of letting emotions free is really important throughout the novel I think.
