1. When someone tells you to be quiet, like late at night, when people are sleeping, so you go to them and try to talk quietly but they keep yelling What? WHAT?! I CAN'T HEAR YOU! It's like... God damnit, You told me to be fucking Quiet..
2. When you ask some one a question, like hmm, I wonder what the heaviest object on earth is, per mass. And they say Earth Duh. and you just... ugh they ruined your conversation based question.
3. When your Writing something, and it gets REALLY REALLY good, and then.. You lose your inspiration and your left with this rising climax of story, and then you write stuff like, and then he got milk out of the fridge and yada-yada becuase you just need to write.
4. When people think your ideas are stupid, just becuase they didn't have the idea, then 10 minutes later they have the same idea and talk about how cool it is.
