There are many things I hate, but for now I'll just write ten examples.
1. I hate people who chew with their mouths open, making a loud slapping sound.
2. I hate people who argue over the stupidest of things.
3. I hate it when your playing search and destroy on Cod4, and when your opponent is defusing the bomb. They spin the camera around in circles, flash their light on and off or shoot their gun into the air. (Don't know why but that always pissed me off.)
4. I hate people who ignore others, just for the sake of being a dick.
5. I hate it when people play loud music in public, is it to much to ask for earphones.
6. Speaking of earphones, I hate it when people do use them, but have the music up so loud that you can still hear it.
7. I hate it when people don't show gratitude when you show them good manners. Example I'm holding the door open for a person but rather than saying thank you, they scowl and put their head up at me in a smug fashion.
8. I hate people who over use sarcasm. (Sure it can be funny, but when a person uses it for everything. Then it just gets annoying.
9. I hate it when a fictional show, talks about a really powerful villain. But when the villain does appear. He gets killed of in a really short amount of time.
10. I hate people, who complain about the food your eating. (You know the kind I'm talking about. The people who go "Eww what are you eating, that looks rotting.")
