In some communities, residents tend to label those neighbors who frequently go out at night and behave strangely as "abnormal" or "suspicious" based on traditional concepts and inherent prejudices against "nighttime activities". People may make the following stereotypes: 1. They believe that these neighbors may be involved in illegal activities, such as crime, drugs or other bad transactions, because nighttime activities are often associated with public security issues. 2. They feel that their behavior cannot be explained by the normal lifestyle, so they classify them as marginalized people, guessing that they may live illegally or have unstable living conditions. 3. Some residents even exclude or alienate them based on this, believing that such people will pose a potential threat to community safety and neighborhood relations. It should be emphasized that this prejudice is often based on appearances and traditional stereotypes, and does not necessarily reflect the truth. In fact, there may be various reasons for a person to go out at night and behave differently, such as night shift work, personal interests, social habits or other normal lifestyles. Therefore, judging based on these external behaviors alone is likely to cause misunderstandings and unfair treatment, and may also aggravate social divisions.
