Catcher in the Rye - Responding to a quote

The following are examples of how you might respond to a quote from the story.

"People never notice anything" (9).

Holden says this, or rather thinks this, when he is over at Mr. Spencer's house getting reprimanded for failing out of school.  It seems to really bother him when someone doesn't see the truth in something, and I think that is what he is referring to here.  For example, he talks a lot about people being phony and how much this bothers him.  I think that the fact that people don't notice things bothers him for the same reason, because people only see what they want to see and don't see the whole, actual truth.  

"I had to sit there and listen to that crap.  It certainly was a dirty trick" (11).

Holden has this thought as Mr. Spencer reads a passage aloud from Holden's exam.  This indicates to me that Holden is embarrassed by his writing.  He refers to it as "that crap", which clearly indicates that he doesn't hold it in high regard.  The fact that he calls it a "dirty trick" seems to indicate that he is upset with Spencer for making him listen to his own writing, which perhaps indicates that he is embarrassed by the quality of what he wrote.  This shame suggests to me that he is capable of better writing, because otherwise he wouldn't feel ashamed.  It also suggests to me that he values Spencer's opinion of him and doesn't want to think about the fact that he turned in such "crap" to a teacher whose opinion is important to him.
