Helping others and caring for them is a noble gesture and reflect one's humanity. I have helped many people in my life with various things. I think it to be the best thing that I can do give back to the world and make it a better place to live.

One such time was when I helped a small child with his studies, specifically his exam, our maid brought her son along with her so that she could keep an eye on him while he studied. He was in the fifth standard and was a weak student causing his mother to be worried about him. I called him up to my study table and looked at his books. With her permission, I sat down to guide him through his course mateial, one subject after the other. After two hours, we both were tired and I asked him to come to me daily from the next day. His mid-term examinations were due in a month and I decied to tutor him for two hours each day till then. I followed a set timetable dedicating time to each subject. I taught him all the important chapters, cleared his doubts, and gave him homework and a lot of questions for his prace. 

He slowly and steadily gained confidance and performed well in his exam. All I did was to help him become focused and prace to become adept at learning and answering questions. He thanked me a lot and I was glad that I could help him with his studies.

In Vietnam, almost everyone, has been a volunteer work and I have too. At my age, I have not been donate blood so I often donate books, toys and clothes for street children and homeless people. I often do this work with my mother. Latest here on Sunday, I with my mother was used to donate books and clothes for a charity organization. In here, I met the orphans children. I played with them. Then I gave candies to them. They were all very happy.Some people think doing volunteer work is waste of time but in my opinion, doing volunteer work help me relax after school and it help me healthy. When I doing this work, I feel very happy to bring happiness to them.
