Taking time you got by these defenses of mine
Though I tried not to let you slip through
And when you worked your way to the back of my mind
It was too late to stop loving you

For my eyes grew accustomed to looking at you
And my arms found a body they hungered to hold
And the rest of my senses surrendered to you
But my heart was the last one to know

Then my eyes saw the warnings they couldn't believe
And my lips felt your kiss growing cold
And my ears heard the stories but kept them from me
So my heart was the last one to know

Now my eyes finally learned to stop looking for you
And my arms slowly turned to another to hold
They could sense you were something too good to be [bad word] But my heart was the last one to know

Yes, the heart is last one to know.
