People are Flawed.
If something involves human beings (as we know them) then there will always be a margin for human error. For some things, this margin is higher, but it doesn't change that people can mess up.
That's often the cause of most conflicts- misunderstanding. No language is perfect. If everyone would just try to understand each other instead of getting offended because of something the other said, then I believe that you'd see a sudden rise in people actually getting shit done.
Now, I may be some 17-year-old sitting at his computer ranting about, but (in the hopes of not sounding too high-and-mighty) I'd say that I'm wiser than a whole lot of people in respect to understanding things like these.
It's unbelievably frustrating to not be able to properly communicate an understanding of something to someone else because you're limited to spoken language, ya know?
Anyway, that's my 2 cents. We should totally use this thread to (try to) talk about ideas like this one. I, for one, find it pretty frickin awesome when you have an epiphany and suddenly get a whole new understanding and appreciation for the world.
