During the day I was very busy building my new home, but in the evenings I often thought about my new situation. It seemed to me that I was the unluckiest man in the world. I didn't have any friends, or any way to get off the island, and nobody knew I was here. There were days when I felt so lonely and sad that I couldn't do anything. I often remembered my father's advice and wished that I,d listened to him For many days I would go to the top of the hill and look out to sea. I sometimes imagined I saw a ship's sail in the distance and hope would fill my heart until I realized it was only the white top of a wave. I felt as sad as a prisoner.
