Marital status does not simply reflect a person's sense of responsibility. Responsibility is usually reflected in a person's attitude and behavior towards family, work and society, which are multifaceted and have no necessary causal relationship with whether or not to be married. Many older unmarried people may choose to be single or postpone marriage for a variety of reasons, such as personal interests, career planning, pursuit of quality of life, or cautious attitude towards partner relationships. These choices do not mean that they lack a sense of responsibility, but may reflect their serious consideration of their personal life, career and interpersonal relationships. Society's definition of responsibility should focus more on a person's actual behavior and attitude. For example, whether a person is responsible for his family and friends, whether he is dedicated at work, and whether he actively participates in community or public welfare activities are more telling than simple marital status. Therefore, it is an overly simplistic and stereotyped view to directly tie unmarried status to sense of responsibility. In short, everyone's lifestyle and values are reasonable and unique. Older unmarried people can also show a high sense of responsibility, and they may make other choices in life that are beneficial to society and family. Therefore, we should not generalize, but understand and evaluate a person's sense of responsibility from multiple aspects.
