Zeke is prescient and always right here. Hmmmmm...let me look in the wife's Psychology book.
My list of Narcissistic personality characteristics
When I see anyone with low self-esteem covered-up by a grandiose presentation, I always suspect a narcissistic personality. These are the characteristics that I look out for:
Rigid, inflexible thinking - Anyone with a different approach is seen as personally attacking the narcissist. Rules rule, and some narcissists get inappropriately angry when they see little things, like grammar errors. I knew a narcissistic computer programmer who would refuse to answer any e-mail that used non-accepted word abbreviations! - ("My way is the ONLY RIGHT way and any other way is WRONG, WRONG, WRONG").
Cannot be wrong - The narcissist is never, ever wrong, and they like to present "proofs" that they are correct. The narcissist cannot accept responsibility for making a mistake and they are expert at diverting the blame to others.
