What type of theme is in this story?
An old fisherman and a young fisherman went fishing. Near the end of the day, the old fisherman hooked a huge fish. The two struggled for an hour to get the fish in their boat. The fish was too strong, though, and it got away. The young fisherman was upset that they did not catch the fish after so much work. The old fisherman laughed and said, “Now you have a reason to go fishing tomorrow—to catch that big fish!”
