What are the motifs in A Beautiful Mind: A Biography of John Forbes Nash, Jr., Winner of the Nobel Prize in Economics, 1994 by Sylvia Nasar?

Relationships, especially between Alicia and John Nash, are a recurring idea in the story. John Nash always had problems with social relationships. As a youngster he would dance with a stack of chairs instead of with a girl. Alicia had been a student in Nash's class and was infatuated with him. She met him again when she worked in the Music Library. This was after Nash had been dismissed from his summer consulting job at the RAND Corporation after his arrest for indecent behavior. Nash did not consider himself a homosexual but he was attracted to men.
