His first bow almost blinded him and he decided that he would spend an entire night shaping a new bow with arrows. By the time he finished the bow and arrow he had worked on it for two whole days and then learned that it didn't work.
Brian was siting by the lake watching the fish swim by. This angered him because he was hungry and needed some meat. Then all of a sudden he remembered that in his biology class his teacher told him that light bends in water. That was why he couldn't catch the fish.
After hours of hard work Brian had finally caught a fish. He was so excited and proud. With his accomplishment he had a new sense of hope "tough hope".
