Fleas are things you usually acquire at home, as a child, by accepting your narcissistic parent's values and mirroring them to him/her. After all, our mirror neurons work independently of our will, and independently of our critical thinking ability at any given time.
However, it is possible to acquire narcissistic fleas by copying both ethical behavior and behavior of lack of compassion and/or morally reprehensible behavior if not seen in a particular context or situation.
We can suppress our guilt and remorse through justification and rationalization, so if you find yourself behaving like a narcissist, it may be necessary to sit down and think about how you really feel about something.
If you can't see through the rationalizations and justifications, if you can't see how something you did or said caused harm to someone else, then you may be a narcissist. More on linktr.ee/narcismeHelp
