One day, a woman suddenly collapsed on a busy street. People around her stopped and looked worried, but they did not know what to do. Then a man who happened to be nearby ran over quickly. He knelt down beside her and stayed calm. A few minutes later, he carefully checked her breathing and put her in the recovery position. He also asked someone nearby to call for an ambulance. Soon, the ambulance arrived and the woman was taken to hospital. She was not seriously hurt, but she felt very shaken by what had happened. She was also very grateful to the man who had helped her. A few weeks later, the woman went to a community centre and signed up for a first aid course. She wanted to learn how to help others in the same way that the man had helped her. She studied hard and practiced the skills many times. Several months later, she had become a qualified first aid instructor and was teaching classes at a local community centre. People of all ages came to learn, and they listened carefully and practiced the techniques together. The woman felt proud and happy that she was now able to help others in the same way that she had been helped.
