     Danny was just tired about the way things were going. His mum came to school and talked on and on about Rick Jackson. It seemed that she would never stop talking. "Somebody's got to stop that boy!" she was shouting. " Rick's troubling everybody in the neighborhood. And he loves to pick on little boys like Danny. "

     Mrs Green, Danny's teacher, was concerned a lot. "I didn't know that Danny was being picked on," she said. " He's never said anything about this to me ! "Mrs Green looked at Danny. "How long had this been going on?" she asked. Danny could only shake his head and look at the floor. He knew if he said a word about this, he would have trouble at school.
