People who:
1. Sing to themselves at any given time at any given space (i.e in classrooms during a test!)
2. People who insist that ****** and nigga are two different things
3. People who believe that only African American people are allowed to call each other niggers (NO ONE SHOULD BE ALLOWED TO)
4. Parents who insist upon arguing, but then get mad at you when you argue back, yet treat it like it's a two sided argument
5. Overly hypocritical people (I, as can many other people fit into this category sometimes)
6. People who interrupt, yet get mad at you when you interrupt them
7. People who spit when they talk
8. People who talk while the teachers talking (or in the case of my school, yell when the teachers talking) and get mad at you can call you rude for actually listening to the teacher and not talking back to you and acting like you have no manners.
9. People who burp without making any attempt to cover their mouths and/or don't excuse themselves
10. People who blow their burps in your direction (not even for kicks, like, they're just the person sitting next to you in class)
11. People who refuse to acknowledge that they burped after letting out a large one
12. Parents who get mad at you for legitimately proving them wrong under the grounds of it being disrespectful (i.e, say your at a party, and you parent's bad memory leads them to tell an untrue story when about how you did something horrible a few months or years back, you see these people forming an opinion of you based on this false story, and in an effort to preserve your reputation, you, as politely as possible, correct them on the story, then they get mad at you and beat you or whatever they do to punish you because you "embarrassed" them at the party when you just wanted to protect your own reputation, and parents wonder why kids are so rebellious -_- {That was a hypothetical example, not a real one just in case you thought I was using a real example but taking out the names })
But yeah, every thing on that list irritates me. That's not to say that there isn't more, and that I never do any of these things, but I still dislike most of them quite strongly.
