I wouldn't. They are so in denial that they will not believe you anyways. They feel that nothing is wrong with them because they have no idea what true love & empathy feel like so they have no idea they are lacking it. You will have the upper hand if you keep your discovery to yourself and use it as a tool. A tool to remind yourself why they say/do certain things, and what their real intentions are. I don't see any benefit whatsoever in telling them that you think they are a narcissist or that you know "their game". All you will do is make them angry or give them reason to try and convince you that you are the one who has problems. They will never respond with "Oh really? Ya, maybe I should get some help." Not in a million years. You could give them every valid reason as to why you believe this and they still will not see it. So, in my personal opinion, keeping it to yourself is the very best thing to do in this situation.
Yes. Otherwise they'll get deeper and deeper into it. At lease they have a fighting chance if you tell them.
A - How do you know they are narcissist? B - Why do you assume that the friend doesn't already know? C - Why do you think they might want to know? D - Is it any of your concern? If you can satisfactorily (and honestly) answer those questions then yes, tell the friend, otherwise leave the matter lie.
Be careful if you do, the narcissist can be a monster to anyone who hurts their pride.
Tell them that you're bored and then say "I know let's play 20 questions?"
It's not best to tell him after a while so be straight and tell him
what can you tell parents that is concern about their children playing outdoor game.
If he or she dates people of the same sex.
Yes, but only if he got something out of it.
Wow...I was wondering the same thing. I know for sure that someone I do not know "personally" is dealing with a narcissist. Yet, I would say follow your gut on this one. If you have had an experience with the narcissist that can actually enlighten the person in question, it may not hurt. It will probably save them lots of emotional energy and heartache down the line. In addition, by chance they have yet to see the signs, your advice may aid in identifying future "red flags"...No.
If they know that you have figured them out, they will not want to be around you for fear that you will tell people the truth. What they really need is help for their problem.
That it didn't work out. The rest is none of their business.
first you need to tell me which Pokemon game you are playing
