My brother, he would do some paperwork in a company, went to a remote village to participate the voluntary activity last month. So my mother was worried about that he could adjust himself to living there. She was dying to hearing from him. Later he told my mother he had fitted in well with the villagers there. However, he told them that a terrible accident had happened. The other day he, who was scared to dead, was about to attend a party while he witnessed it. Worse still, the car fled from the scene. Firstly he called, urged the doctors to rush to the spot and then he gave first aid to the injured. Eventually the injured man was lucky helped out of danger.
I am proud of him, who is occupying himself with his work and devotes himself to helping those in the need.
