Sincerely

I could tell you I came by to say hello
But I knew good and well
That you weren't homeNow these lines I write
Will reach you by midnight
Tell you that it's over, anyhow
Sincerely, too late to turn back nowBlue words on white paper find a way
To say what I'm not strong enough to say
If I stay to say goodbye
Someone's bound to cryAnd I don't think that
I can stand to hear that sound
Sincerely, too late turn back nowI don't need to sign my name
'Cause you know me by now
And I won't have to take the blame
When tears come falling downI just ain't got the heart to hang around
Sincerely, too late to turn back now
P.S. I guess I let you down
