what kind of people do you dislike?

i have a lot of dislikes but what i hate most is the people who are fake or plastic, backbiter. I am really a true person so thats why i dont like pretention. If you have something to tell then better said to me personally and not at the back. I value very much friendship and i give my trust but when someone broke it its hard to gain it back so in short i dislike traitor. Definitely i hate also cheaters, who ruins relationship. Its a big betrayal for me.

I don't like people who are. 1.) backbiters 2.) plastics (shows different personalities depending on the current group) 3.) heavy drinkers
