Ever encounter a person like this?

It’s really difficult to talk with people like that. We’re individuals and it’s normal to have a difference of opinion on things. We can’t all always agree all the time, it’s impossible. Sometimes there is no right and wrong way to think, either; we just have different priorities. Relationships like this can become really toxic, from my experience.

My mother is like that. I once told her that I don't like Miracle Whip so I use real Mayo. She flew off the handle saying I am an asshole and don't know what's good. That is what narcissists with very fragile ego's do.

Sure, it’s an unhealthy environment to be in, I had to distance myself from such people.... it felt like coming up for air from being emotionally under water.

yes I know that. Incredibly unhealthy people with very fragile egos.

A lot of people in their youth are like that, some just never get mature on that field

I dont think I've experienced that, thankfully.
