He was trying to catch a bus. The bus left without him. He was running. He tripped and fell. He was lying on the sidewalk. "Are you alright?" a girl asked. He was holding his arm. His arm hurt. "I think I broke my arm," he said to the girl. The girl dialed 911. "Help is on the way," the girl said. She helped him up. He sat down on a bench. He wondered why he fell. He looked down at his shoes. His laces were untied. He always forgot to tie his shoes. He never imagined breaking his arm. He started to tear. His arm was in terrible pain. "The ambulance is coming soon," the girl said. She felt bad for the boy. She had broken her arm before. She knew how much it hurt. The ambulance arrived. The paramedics took the boy. "Thank you," he said to the girl. "You're welcome," she replied.
