    As the saying goes, many little drop of water make an ocean. A small action may lead to major changes took place in society. My friends and I had participated in a voluntary activity at a nursing home last week. We first did some cleaning or washing. After that we spent half an hour chatted with the old people living there. Though it was a tired day, we were happy with that we did. I felt a sense of responsibility by visiting the old. If all of us lend a helping hand to the people in need, they can live in harmony with each other. A society is just as a family. If we are willing to help others, our small actions can make big difference.
