There's a secret behind the smile you see
For this smile is just a part of me
But I know some can't see the signs
That show I'm hurtin' all the time
And the lonely know my secret
They know you're on my mind.

There's a secret behind the lies you tell
For inside is where the sorrow lies
Cause I'm living like the lonely do
For they've lost someone they love too
And the lonely know my secret
They know what I go through.

There's a secret behind the smile you see
For this smile is just a part of me
But I know some can't see the signs
That show I'm hurtin' all the time
And the lonely know my secret
They know you're on my mind.

Yes, the lonely know my secret
They know I still love you…
