This shows a reminiscent side of Pi. He wishes that he could've said goodbye to his family, and he wishes he could've said goodbye to Richard Parker. However, he realizes that "life is an act of letting go."
"Even when God seemed to have abandoned me, he was watching. Even when he seemed indifferent to my suffering, he was watching. And when I was beyond all hope of saving, he gave me rest. Then he gave me a sign to continue my journey." Life of Pi.
