Few things that people do to irritate me

I have a few certain things that people do to push my buttons that irritate me: talking behind my back, budding into my conversations, and trying to fight or start an argument when there is no reason to be fighting or yelling. I don't like any of these things that people do. They annoy the heck out of me to the point that I don't want to be waisting my time. To solve a bad situation around me I would walk away and not say a word to the person that is saying or doing negative things that I don't appreciate being disrespected.
