[Verse 1]
I should know by now
You don't really love me
Or think that highly of me
I should know somehow
You don't want me only
You just say that when you're lonely

[Chorus]
I hear your voice and I forget again
That your "Hello" means "Goodbye" in the end
Still I believe somehow
But I should know by now

[Verse 2]
And I should see the light
But it's so hard to do
When all I see is you
And I should do what's right
But I keep on believin'
This time you won't be leaving

[Chorus]
I'm just a fool, a fool where you're concerned
But that's a lesson I can't seem to learn
Someone show me how
'Cause I should know by now
[Instrumental Break]

[Chorus]
I'm just a fool, a fool where you're concerned
That's a lesson I can't seem to learn
Someone show me how
'Cause I should know by now
