Do you have any people in your life that annoy you just by being themselves?

I swear, my mother can completely ruin my mood with one phone call. She’s completely neurotic and I can’t help but get frustrated with her within seconds of being in her presence. I simply don’t have the patience for high strung people. It’s almost comical how pissed off I get just by being on the phone with this woman. Never in my life have I known anyone else that made me feel this way. I just want to scream at her to calm the f*ck down, shut up for five minutes, and just breathe – but I know it won’t work. Everything is a huge ordeal for her. I strongly suspect some type of mental illness, but I’m not sure which one.

Whew, rant over.

So, what about you? Do you know someone that can make you feel like ripping your own fingernails off just by talking to them? What is it about their personality that’s so frustrating? Examples of such behavior?
