It's essential to clarify the terminology used in this context. The term "narcs" could refer to two different things: "narcissists" or "narcotics/narcotics officers." Given the second part of your question mentioning young girls smiling, I'll assume you are referring to "narcissists" rather than drug enforcement officers.
Narcissists are individuals who have a personality disorder known as narcissistic personality disorder (NPD). People with NPD typically exhibit a pattern of self-centeredness, a grandiose sense of self-importance, a need for excessive admiration, and a lack of empathy for others. They often manipulate and exploit others to meet their own needs and desires.
Regarding the feelings of paranoia around others, narcissists may make you feel that way due to their manipulative and controlling behavior. They may use tactics like gaslighting, where they distort or deny reality to make you doubt yourself and your perceptions. As a result, you may become more cautious and unsure about what is real and what is not, leading to heightened feelings of paranoia and insecurity.
Regarding the "kick" they might get from young girls smiling at them or any other type of attention, this behavior ties into their need for excessive admiration. Narcissists have an insatiable hunger for attention and validation. They seek to maintain an image of superiority and attractiveness, and receiving positive attention from others, especially those they perceive as vulnerable or easily impressed, feeds their ego and boosts their self-esteem.
It is essential to remember that not all individuals who enjoy attention are narcissists, and not all narcissists exhibit the same behavior. However, if you find yourself dealing with someone who consistently exhibits manipulative and exploitative behavior, it's essential to set boundaries and, if necessary, seek support from friends, family, or mental health professionals. Dealing with narcissistic individuals can be challenging, but understanding their behavior and maintaining healthy boundaries can help protect your well-being.
