Children need parents and vice versa. When an old man, as strong and powerful as he was when he was young, still in his old age needs children and others.
When a sick person also needs a doctor. Even a president even needs a barber and a medalist. That is the wheel of life, giving each other and receiving. Sometimes a person gives help and sometimes a person receives help. Therefore let's really realize this, that people need each other.
Everyone should be aware that they are social beings with social responsibility both to the environment and to others. Social responsibility towards others include protecting, respecting, promoting, and others. Therefore, when viewed from the aspect of social responsibility, everyone should appreciate others and treat them well.
