Peter was walking back home from school, thought about the class today. It was about giving the first aid.
Suddenly he saw a young girl lying on the ground. She seemed to be asleep, so Peter saw what her face was
very pale. He went up to the girl and found there was a cut on his left leg, and blood was bled out. He knew
what he should do next. He dialed "120" immediate. While waiting, he took out his handkerchief and try to stop
the bleeding. He put the girl in the recovery position. "She will be right," he thought, when the ambulance arrived
five minutes late.
