How is the theme of independence further developed on pages 109 and 114?

In "Prisoner on the Hell Planet" Art feels an unbearable sense of guilt over his mother's suicide, facilitated by the fact that his relatives seem to blame him as well. His cardinal sin, he feels, is one of neglect. This is poignantly driven home through Art's memories of the last time he saw his mother alive, when she came into his room and asked him if he still loved her. His answer, a dismissive "sure," is a constant reminder of his perceived neglect. Art's guilt over his mother's death is noteworthy for its similarity to the guilt that he feels regarding his father.This sense of guilt and neglect are shared motifs throughout the book. All the characters feel it and it is this interdependence of sorrow that ties the narrative together.
