Acceptance is one of the stronger themes in Ishiguro's novel Never Let Me Go. It is also one of the more annoying themes, according to many critics. The theme is played out through the characters who are clones, such as Kathy, Ruth, and Tommy. Though they sometimes have questions about their existence and the roles that they play as organ donors, they accept their plight without a fight. Although Miss Emily, the head of their boarding school, and her accomplice Madame, attempt to prove that the student/clones have souls by encouraging them to produce art and then displaying it, there is no discussion about the clones' rights in making decisions about their lives. They are told they are organ donors, and the clones go along with this determination made not by themselves but the adults they look up to.
