Dumb lyrics

You know, these words sound right
When they were in my head
But when I start to speak, you know,
They sound quiet dumb instead
Wish I could make myself clear to you
But my words never sound the way I want´em to
[ Lyrics from: http://www.lyricsmode.com/lyrics/f/futuro_incierto/dumb.html ]
You never get it right
I know it is my fault
Can´t never explain myself
I can't explain myself
As I start to speak my brain disconnnects
Can´t never explain myself
I can´t explain myself

Sometimes I wish I just should shut my mouth
But then I find there really isn´t shadow of a doubt
And when I start to speak is bullshit once again
No matter how I try to get to you it is vain

(X2)
You never get it right
I know it is my fault
Can´t never explain myself
I can't explain myself
As I start to speak my brain disconnnects
Can´t never explain myself
I can´t explain myself
