Do You Really Know?

Do you know,
Really know,
What you think,
You know,
Really know?

Maybe you just think,
That you know,
When you don't know,
What you know,
And what you really don't know.

So do you think,
That you can know,
What you really,
Don't know,
When you don't want to know,
That you don't know;
And that you will only know,
When you accept that you,
Really don't know.

So do you really know?
