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.
