What do you really hate about other people?

Usually I don't love the ones who is very rude and who is selfish. I thing it is very difficult to cop up with such person. If a person do not have such a character it is very easy to have a good friendship with him and I had find this from my life

Me too. I hate arrogant people who thinks only about their selves. I used to have a friend before, she's so talkative (but that's not the problem), she always talks about herself and brags about how she's so pretty and how so many guys love her (As if! She's not even noticed by the guys in our neighborhood!), and she doesn't let other people talk because she has so much to say about herself. I mean in our neighborhood, we are 4 girls who always hang out together, and she's the one who always wants to talk, and she doesn't let us speak because she's always talking.

I really hate people who pretend to be someone they're not. I don't know, it irritates me when they put on a facade just to be liked more. There's this girl, she is unnaturally happy and talks too loudly even though I know she's shy around people and usually only befriends quiet people. I used to be irritated at her attempts to befriend me. I did like it when she wasn't so loud, and when she was just herself. I enjoyed that part. Eventually, she's now a good friend of mine (mostly because she's friends with a lot of my other friends). I like her more. She's actually a pretty cool person, even when she's being fake. I learnt that she's just insecure from her past experiences. Yeah. Anyway. I don't like fake people, but I make exceptions if I learn they're actually pretty cool people.
