What's to be mad about???
I think my neighbor has a gun therefore I'm planning to invade his house (he doesn't seem to like me anyways) if he gets hurt, oh well, that's "War". OK, he's not really my neighbor, he's on the other side of the world but it's still Self-defense, get it?
OK, I don't really think he has a gun (and if he does I may have sold it to him awhile back) BUT he has some stuff I want and me and my "friends" are bigger and badder than him and his. Get it?
OK, I suppose I could just go over with a sixpack and try to befriend him instead of this "War" thing but then I wouldn't get his stuff, get it?
