I agree that parents should teach their students must be a good citizens, as early as possible give lesson how to be a good citizen. The main teacher for the child from parents, because the parents are the role model for their children. The way teach them throught habituation in house, instead how to interaction with their parents, sibling and other families. The parents can begin teach them that we can make comfort and dont disturb the other people. it is same we keep safety environment. The child should respect the other people .
