15. They Have Difficulties Forming Relationships
Relationships require trust and compromise between people in order for them to work. However, these two concepts are alien to narcissistic personalities who are unable to work out a middle-ground when interacting with other people. Their extreme sense of superiority over others prevent them from accepting anything they think of as inferior, creating friction with family, friends, and peers.
On top of their inability to see eye-to-eye with other people, narcissistic personalities also feel easily slighted when people fail to agree with them. This makes them distrustful of others, thus driving a wedge between them.
