The catcher in the rye

In a extract of the book that we read in class we could analyze a lot of personal characteristics of the protagonist (Holden). What he was saying in the stract is that we should not have the tradition of burring our love´d people in a cementary to remember them, or for example, what is the importance of putting flowers on  the place? With this stract I could analyze this situation that is so normal and so traditional that I´ve never made a reflection about this specific situation.
