It comes from the fact that I am not NPD. I am bipolar,but not crazy.

I do have NPDS in my family and know a lot of them in life.
My ex-h would be an example.

I am not talking about anyone of here- but-

I think some people can see thru the delusional ideas of people with NPD. Some NPDs throw temper tantrums and can appear very childlike and spoiled.
