Frustration

I get easily frustrated when faced with people who don't know how to think. I need someone who can think and question to have a real conversation. People who only know how to follow or obey tend annoy me. Especially when they show an unwillingness to learn or possibly it's an inability, I'm not sure. It's always hard for me to figure out what's wrong with a person when they seem and look normal in every way and then seem extremely stupid. Ignorance is the lack of knowledge, not the inability or unwillingness to learn. I will admit that I'm ignorant about lots of things. However, that being said, I make sure to learn at least one new thing every day. I read. I surf the internet. I look up information when I realize I don't know anything about something I have a question about. I don't understand people who don't have a desire to learn. Most people who think they know it all (and aren't even close) tend to also suffer from narcissistic personality disorder, or so I've read. Which doesn't surprise me. Thoughts?
