Dead Bird
Very early in the story, Susan is looking out a window toward the cars in the parking lot half-hidden by swirling dust. Without warning a bird crashes into the glass and drops dead to the ground. The death of a bird has along history as a symbol of impending doom.
Susan’s Glasses
Susan’s eyeglasses are perhaps the most complex symbol in the book, working ironically in a way. She sees more clearly with her glasses on, obviously, and is moved to make wrong decisions when she takes them off. At the same time, however, she is herself seen differently by others when she is not wearing the glasses.
Wind
A strong wind is ever-present throughout the book. Its symbolism is explicitly addressed in the inscription upon a college ring: “The winds of freedom blow.” It is in the form of the freedom which this wind blows into the story that is up for grabs.
Ophelia
The primary topic of study in Mr. Griffin’s English class is Hamlet. And the primary topic of study within the play is Ophelia’s relationship to Hamlet. The symbolism lies in the fact that Ophelia is singularly devoted to Hamlet who rejects her. This reflects Mr. Griffin’s singular devotion to his students who reject him.
Mr. Griffin’s Tie
Mr. Griffin explicitly infuses his necktie with symbolism, suggesting it represents dignity. In reality, Griffin’s appearance and the demeanor it helps to project are not viewed as expressions of dignity by his students, but as further representations of his hated rigidity.
