Such an ego...at last I see the truth

Merriam-webster’s definition of superiority complex is:
“an exaggerated opinion of oneself”
Wikipedia describes it as:
” a subconscious neurotic mechanism of compensation developed by the individual as a result of feelings of inferiority. The feelings of inferiority in this specific complex are often brought on by real or perceived social rejection. (your ex husband????)

My translation — these people have SERIOUS ISSUES!
So they have issues, but how do you deal — on a day to day basis — with that irritating and really annoying pretentious, self-righteous, egotistic or snobby relative, friend, co-worker, partner or new man or woman you just met and want to get to know?
There are three ways you can deal with people who act like they are better than everybody else.

1. One way is roll your eyes, show them the palm of your hand and say, “Pull-ease!” Then ignore, avoid or totally cut them off from your life. This one is probably the easiest of the three ways of dealing with these types of people.

But that doesn’t help if you are in daily contact with this person — or even like and love the person. That’s lots and lots of eye rolling, palm showing and ease-pulling!

2. Another way is unmercifully hit them on their weaknesses, painful past and anything to expose them for what they really are and reduce them to nothing. That’ll bring them back down to earth. And when the tears start rolling down his or her face, gleefully rub your hands. Mission accomplished!
But there is a problem here too. This won’t do you any good. Some of these people are so deluded that they’ll just think you’re jealous and envious !!!! -----   Almost her exact words!!! — and yes, have an inferiority complex. Even worse, most of these “superior” individuals have become such experts at putting others down !!! -----  she has and does!!! , that they’ll hit you back so hard that you might find yourself not just down on earth but trying to dig a hole in ground — with your teeth. Trust me, I’ve been there.

The other downside is that if you’re a naturally good-hearted person (superiority complex?) you’ll end up feeling like a monster for making such a good looking or intelligent or rich or sweet or whatever [superior] person feel small!
3. The best way is come to terms with the fact that you are dealing with an oversized ego that is out-of-control, so you’re not likely to get the person to change his or her behavior. The only thing that you can change is your reaction.
