Kids,or better say teens who act like they own the world. Seriously some kids I've seen, mostly at skate parks act like they are God's gifts to the world. Seriously,someone clearly isn't being a very good parent there. They have no respect to older people.
Also,kids who smoke,I've seen kids smoke under the age of 13. Under 13!!!! And it's just because of the way this world is becoming,where it's considered 'cool' to smoke and drink. Seriously,I know smoking is okay when you do it because it calms you down,but these kids are clearly just doing it cause it's 'cool'.

Also,stupid people on the road. They never cease to amaze me. Just yesterday this woman almost pushed me to the sidewalk.

People who act cocky on the internet.
I hate it when someone is staring at me while I'm eating. Don't know why,but it really bothers me.
When people start taking advantage of you and then when you tell them you won't do it anymore,they get mad. Seriously, it's their won fault they even get so dependent of me or someone else.
Trolls in online games.
When someone talks bad of the things I really like. (for example TLK)
When people
think they can do everything better than you can.
People who can't handle their dogs and haven't trained them properly.
They way some people from my college act in front of girls. >_>
