Pi's main regret about Richard Parker is that, at the end of their journey, Richard Parker left without saying goodbye. "I was weeping because Richard Parker left me so unceremoniously." He concludes with "That bungled good bye hurts me to this day." Pi is hurt because he and Richard went through the most horrible circumstances and in times of great struggle, people form significant bonds. Pi is also someone who constantly seeks order and answers. He notes that the book is divided into 100 chapters. He likes order. One reason that he is interested in religion and science is that they provide a wide variety of explanations and closure to many of life's questions. When Richard leaves without a word, Pi feels like this is a missed opportunity for closure to one of the most traumatic relationships and experiences of his life.
