I've worked for many years now with a woman who sounds like your description of this person, Barx. We are both teachers, she is in the room next door to mine, on the same team, and I have had to deal with her daily. The only positive to having to be around such a person daily is that I have learned to dismiss her quirks and insults, and now I'm immune. I also feel kind of sorry for her. There certainly is a narcissistic element to such people. Each time I'd try to engage her in a conversation on any topic other than herself, she would cut me off, yet she would expect me, and everyone, to listen spellbound while she recites ad nauseum boring stuff about herself...always herself. You would think after years of this, she would start to think about how she relates to people, how judgmental she is, how self-centered, but NO...and so one learns to just let her opinions, judgments and long self-centered monologues go unacknowledged. I still lack the rudeness to just cut her off (as she does me), or walk away (as she also does). The good thing is I'm retiring and won't have to be around her anymore, but, as I said...I've learned to just let it roll of my back and not be victimized by such a rude person. I hope you can adopt this attitude.
