nitpickers, perfectionists, and people who constantly find ways to put you down and left them up. Also people that get annoyed at everything or are constantly angry. lastly people that refuse to engage in an intelligent discussion when disagreement arises. I'm referring to people that toss catch phrases like "talk to the hand" or try to think up comebacks or trap you in your words, or rather than simply talk and try to come to an understanding. people that keep forwarding bullshit that has been proven wrong by snopes since forever. an example is I still see people forward horrible pictures of deformed sick babies, because facebook will donate money for every forward. That shit makes me want to punch them through my computer screen. Also self righteous, smug and pompous people. (basically anybody that thinks they are above you and make sure you know it) Also people who talk too softly and then when I ask them what they said, say never mind. just a heads up. deaf people and hearing impaired people hate you every time you pull that shit.
thats all I can think of right now.
