If people think world peace will ever happen you are shitting yourself. World peace is a nice thought but not very likely. We are animals and we act like that some times. I think we, as the world, could achieve something that mimics world peace but isn't. It'd be more like a mutual understanding and will to not fight, but there will never be peace unless there is understanding. Understanding of ethics and religion. Not a shared understand, but an understanding. A bit like how you explain what agnostic is. Agnostics don't believe, but don't hold it against you, if you believe.
My biggest pet peeve is people who eat with their mouth open. There is even a word for it in Danish. "To eat with your mouth open" = "at smaske" I hate hate hate it when people do it. It's that whole say it don't spray it, but with food. I really don't like to see what you're eating or hear that you're eating. It's like those people who chew gum really loud or always pop their gum. HATE IT!!! I have other pet peeves, but none compare to that one.
Well.. it depends on my mood and who I'm with, but normally I pick dare. One it's funner, two it's enteraining to those around you and three truth isn't all that appealing. If you pick truth you could end up revielling something you didn't want to reveal. So I tend to pick dare. The only time I pick truth is when I with these 2 friends I have, because their dares tend to be out of my confort zone. E.g they dared me once to go out in the yard with no clothes on or they dared me to show them how I'd give a lapdance... things like that.
