Salva was very responsible and resourceful because before he went to school he had things to do such as taking care of the cows with his younger brother Kuol, and Salva took care of all cows that his father owned while Kuol took care of only one.
At this point Salva changed to being brave because he had to cross a crocodile invested river. There was also soldiers that were shooting at them. He had hope and he made it. He felt really nervous because of the crocodiles and the blood stains in the water
Salva had changed to being generous, respectful, and thoughtful because he was now saving thousands of people from the dirty water in Sudan (thats how his father got sick) He even did it to the village that attacked his uncle. He is now saving people by drilling wells in the villages.
