Both narratives begin with the theme of prejudice. The first scene of Romeo and Juliet touches upon the long-standing hatred of the Capulets and Montagues. As soon as the "star-struck lover," Juliet, learns that Romeo is a Montague, she acknowleges this bias, "My only love sprung from my only hate! (1.5.).
