Behind the eyes

I sometimes feel the need to knock
Before I enter into my mind
And sometimes need to excuse myself
For things that happen inside my head
I often wonder what really goes on
Behind my eyes where I cannot see
And I can't remember which is true
The thoughts I thought or the words I said
I sometimes feel that I spend too much time
With a single thought while neglecting the rest
But then I remember that thoughts don't care
If they are first or if they are last
And sometimes I think that I think too much
But don't allow others to see my thoughts
I don't think that people will listen to me
Because what I can offer will fade too fast.
