Who Really Knows

I know
Do you know
Do they know
You just think you know
That I don't know  
But I know
You think you know  
That I don't know  
They know
But not yet, they will know  
They just want to know
But they don't know
Not yet, that you know
They'll learn to know
But as soon as they know
They will know
They really don't know  
Because only I know  
It will seem I don't know  
And all else will know
But I alone will only know  
What you think you know
And what they think they know  
They know
They don't know
They don't know
That they will know
You know
You dont know
But you don't know  
You will know
And when they know  
That only I know
They will finally think they really know
Wrong again, they don't know
You dont know
And they don't know
But you know  
They don't know  
And they know  
You dont know
But do you really know
You'll just think you know
And they'll think they know
But only I really know
And when you think you know
That they know
You'll realize you don't know  
Because they don't know
And when they believe they know
That you know
They'll realize they don't know  
Because we all know
You dont know  
And we all then know
That only I know  
But if you know
I know
And they know
I know
Then you know
And they know
Only I know
And then we all will know
But I know  
We all don't know
Because you don't know
And they don't know
That only I know
You just think you know
And they think they know
But the only way to know
Is when I don't know
Then all will know  
When the one who did know
Is not around to know
