You start walking.  “’Ey!” The officer calls, but you don’t look back.  Suddenly, you slip on a wet patch of grass and do a full split.  You hear something crack.  “Ohcrapohcrapohcrap,” you think.  “Help!”
The officer and the guy rush over and pull you up by the arms.  You’re on your feet… everything seems fine… you take a step and hear something else crack.  This something is bigger than the other something and now your legs feel as useless as a jellyfish hot-glued to your torso.  “Augh!” You fall down again. 
The officer keeps dragging you by one arm, he may have dislocated your shoulder by now, but whenever you protest he says, “you just want me to go easy on you!”  Eventually he pushes you into the back of the police car and the guy helps to arrange you more comfortably.  “Imma takin’ you in, now, boy!  Leavin’ the scene of an accident is serious!” he looks at the guy, “you don’t have to come.  Go get your truck fixed, boy.”
