Misunderstanding/major ignorance. Especially with pure stereotyping. This was something else pretty annoying:
http://www.eface.in/denmark-is-a-big-shame-to-whole-world/ Long story short, there are no 'calderon dolphins'. The whales in the pictures aren't endangered, and are the Faroe Island's chief source of food, supplies, and income. It's like telling the Middle East to stop producing oil, or China to stop manufacturing goods. The misinformation makes me want to rip my hair out.
I've also been running on around 5 hours of sleep each night for the last few weeks, studying my tushy off, etc. My history teacher gave us a two projects, a large homework packet, and 7 extended answer questions on Friday, all due on Monday, along with crap tons of other homework in other subjects. I don't complain about homework, but when I'm stressed and my parents start yelling at me for getting a B on a test, telling me to study harder, etc I get really really pissed.
A teacher, who I thankfully don't have, assigned a 3 page essay. The catch is that you need 20 first person sources, 10 secondary sources, and 30 pages of notes, handwritten. God damn, what kind of homework is that? He's a history teacher, and has done his best to destroy it. History is my favorite subject, and it get's me really annoyed when it's taught incorrectly, such as by turning it into blind memorization.
Plenty of screwed up kids in my school that are really disrespectful. E.G, there are people who when walking in your direction, will intentionally shove you out of the way, rather than walking around. And I don't mean accidentally walking into someone. Normally when two people pass each other, they naturally get out of the way. In this case, when one party moves out of the way, the other intentionally screws with you. It's like they have to act larger, be louder than everyone else. They don't bother me, or target anyone specifically, it's just annoying when someone who's just minding their own business get's yelled in their face, then shoved out of the way. Thankfully they're a minority, and their tactics haven't seemed to gotten them any popularity either.
