Why do I even bother talking?

I hate people. I have decided that. I hate that they don't listen when I try to help them, I hate that they treat me like shit because I am the tech support person who answers the phone, I hate that they can't manage to follow along when I am trying to walk them through something. Most of all, I hate them because they are helpless. 90% of my calls are stuff that would be answered if they would READ the f-ing documentation we have worked so hard to write. Is that so hard to do?
