Each nation has many good people who take care of others. For example, some high school and college students in the United States often spend many hours as volunteers in hospitals, orphanages or homes for the aged. They read books to the people in these places, or they just visit them, play games with them or listen to their problems. Other young volunteers work in the homes of people who are sick or old. They clean up their houses, do their shopping or mow their lawns. For boys who no longer have fathers, there is an organization called Big Brothers. College students and other men take these boys to baseball games or on fishing trips and help them to get to know things that boys usually learn from their fathers. Some high school students take part in helping disadvantaged or handicapped children. They give care and comfort to them and help them to overcome their difficulties. Young college and university students participate in helping the people who have suffered badly in wars or natural disasters. During summer vacations, they volunteer to work in remote mountainous areas to provide education for children. Each city has a number of clubs where boys and girls can go to play games or learn craft. Some of these clubs show movies or organize short trips to interest. Most of these clubs use a lot of high school and college students as volunteers because they are young enough to remember the problems of younger boys and girls.
