Knowledge

There are people who know that they don't. But still hesitate to ask.
There are people who that they do, but hesitate to come forward.
There are people who don't know that they do, they live happily.
and there are those who don't know that they don't ... well lets not talk about them.

A little knowledge is a dangerous thing, but no as dangerous as a lot of knowledge. Alot of knowledge can kill you for God sakes. The only word that is making the whole world angry is "WHY".
