I can understand the scenario you're describing.
In real life, encountering someone who exhibits narcissistic or psychopathic traits can be challenging and unsettling for those around them. People with these personality traits may display manipulative behavior, lack of empathy, and a sense of entitlement, which can make others feel uncomfortable or even threatened.
In public settings like a bus or train, encountering such individuals may raise concerns for others' well-being and safety. It's essential to remember that it's not uncommon to encounter various personality types in public spaces, and most people do not have a diagnosable personality disorder.
If you ever find yourself in a situation where someone's behavior is causing concern or discomfort, it's best to prioritize your safety and the safety of others. If you believe there is a potential risk or danger, you should report the situation to the appropriate authorities or seek help from law enforcement or transit personnel.
It's important not to diagnose or label individuals based on limited observations, as diagnosing personality disorders requires a comprehensive evaluation by a trained mental health professional. Instead, focus on being aware of your surroundings and supporting a safe and respectful environment for everyone.
