Now there's a thought -
Let me give you an example when an ex and I decided to take an IQ test for fun - I scored more than him although he was the resident genius - and the comeback was "Do you for a moment think this gives actual results - I have way more knowledge than you do"
Okaaayyyy
I doubt anyone who is in denial would take the test and actually agree that they are in fact a narc even if the test says so -that's just how most of them are (perfect)
I can go on - you know I can on this particular topic lol
