What is an example of symbolism in the novel, Words in Deep Blue?

The Last Night of the World symbolizes one’s values in this novel. Though the event is named after a short story by Ray Bradbury, this is barely relevant. In actuality, the students at the high school in Gracetown decided that they should collectively pretend that a single night was the last ever. They acted like the world was going to end the next day, and they must do all they want to do with no thought of consequence, in one night. Thus, the two times that characters in this story have one of these events, they are far more daring and focus on their top values. The first time Henry goes through one of these nights, he abandons his plans with his best friend Rachel, even though she is about to move away. At the time, his top priority is to spend time with his crush, Amy. The second time, Henry is careful not to abandon Rachel, and spends a meaningful night talking to her. This reflects the shift in his values over the years.
