Why does Kino sometimes wish his father were a fisherman and other days glad that his father is a farmer?

kino enjoys life every day, going to school in the village during the winter and helping his father on the farm during the summer. Jiya also stays busy, helping his father fish, and sometimes, Kino accompanies them. Fishing is exciting to Kino and, at times, he feels Jiya is luckier since his father is a fisherman, but Jiya's father tells him they need both farmers and fisherman. On days the water heaves, Kino is glad his father is a farmer, never forgetting the cold still water under the warm blue surface.
