One evening you were walking in the park and reading a book, walking at a slow pace and enjoying every second. But suddenly, a guy caught your glance. He sat on the curb and wiped the blood from his lip. His hands were rubbed until they bled, and his pants were torn at the knees. Perhaps he got into a fight, or fell badly. Whatever it was, you were raised to be a friendly and helpful person, so you approached him and stooped to his level to ask him everything and offer help. Will you do this or will you leave him alone?
