Mark and his grandpa loved going fishing together. One Saturday afternoon, they packed their fishing gear and headed to their favorite spot by the lake. Mark's grandpa taught him how to cast his fishing rod into the water. As they sat by the water, Mark felt the warm sun on his face and listened to the birds chirping. He loved spending time with his grandpa. They chatted and waited for the fish to bite. After a while, Mark felt a tug on his line. Excitement filled him! With grandpa's help, he reeled in a shiny fish. It was a beautiful rainbow trout. Mark was so proud of himself! They caught a few more fish that day. Grandpa taught Mark about patience, nature, and the importance of taking care of the environment.
