Who really isn't?

I HATE PEOPLE WHO DO THIS! Whenever they're wrong, and you're right they allude to you being a smart ass or to you not knowing something else. May I say, at least 79% of the time someone else knows more than I do. So just give me ONE moment of validity. Knowing that someone's always better than you, is pretty much my insecurity and reason for me to do anything; aka, for me to be in NAHS, or at least try to be in NFHS. So, I guess I don't do anything unless I want to feel better. So that's it. I'm selfish. I'm very very self-centered. but who isn't?
