h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

I have a strong dislike about people who think there better than other people. Know, I know everyone including myself always do this a little, but some people I tell ya, jeesh, you could have a PhD in Quantum Mechanics, and they could have a P.O.S. in... hmm, Physical Education, and they'd still think you know more than them. Which brings me to my thesis (which in fact isn't really a thesis, it's just something i thought might be interesting to hear from other people than just myself.), Can your pet peeve (where ever did that phrase derive from?), also be your favorite thing, or your best friend?

Know, I ask this, with addition from my nice little paraghrap above, because my best friend is exactly like this. You see (don't worry, I'm not some old lady with a tale on an airplane when she's cornered you in and you want to hang yourself), my friend (name not going to me mentioned because he might see this and I don't want to insult anyone) thinks totally that he is better than everyone. Now, I used to try to just hold in my anger about it, but it finally came out in a burst of very bad and mean behaiviour, so I talked to him about it. I told him that if he doesn't stop, at least to me, then he's going to have a shitfest of a life. It didn't help anyone else much, but at least he respects me, and another one of his closer friends. But he still does it to other peoples, and it really isn't very nice. Your thoughts?
