Janice was on cloud nine. Starting from today, she would be going fishing with her father every Saturday. Janice had always wanted to go fishing. She liked to feel the cool breeze blowing on her face. She was always in awe of the many colourful fish that made their home in the sea.
Janice checked her fishing equipment again. Everything she needed was in her haversack, neatly packed as they had been three days ago.
Hearing her father call her, she dashed down the stairs and into his car. Janice could not stop talking about the fishing trip on their way there. She wanted to catch a big fish for dinner that night. She also wanted to compete with her father to see who could catch up on her other favourite activity – reading. Janice’s brother did not like fishing. Not only did he feel that it was too time-consuming, he also felt that little skill was needed for the activity. “It’s all a matter of luck,” he always said. “You just leave the rod at one stop and wait for the fish to bite” Janice disagreed with her brother’s point of view. She knew that different types of fish needed different types of bait. She also knew that experienced fisherman would know exactly which part of the ocean contained the species of fish that they were interested in, the fisherman had extensive knowledge of marine life. They had knowledge of the food chain which they used to determine where the fish were located. Knowing that dolphins ate tuna, they knew that they would be able to find tuna where the dolphins usually lived.
When Janice reached the pier, she took out her equipment and ran towards the boat her father owned. She could not wait for the day to start.
