Life's full of things that seem to leave few choices,
You learn a lot just by necessity,
You see that good can speak with many voices,
With many words, you hide the faults you see,
You open up when you think there's safety,
You run away when the danger is clear,
And people judge you by what circumstances they hear...but
I know you better.

'Cause I know you by heart, I know you by heart,
Yes, I know you by heart,
I know you better than you know yourself.

You have a memory that light-speeds backwards
to every pain and pleasure in your heart,
No one can camouflage their feelings better;
for your survival, you have learned the art,
You flash those eyes - they see a beast inside you,
You sympathise - they glimpse a shining saint,
You show a side for the effect that you calculate...but
I know you better.

'Cause I know you by heart, I know you by heart,
Yes, I know you by heart,
I know you better than you know yourself.

I know you by heart,
I know you by heart,
I know you by heart, (ooh, yeah)
I know you by heart,
Know you by heart, (and I know you better)
Yes, I know you by heart, (well, I know you, well, I know you)
I know you by heart,
Yes, I know you by heart,
I know you by heart, (I done know you by heart)
Know you by heart,
I know you by heart...
