I know you know that we're through
I know you know what you've got to do
Knowing it, showing it's just a part of it
But I got a clue
It ain't what I know that makes me blue
It's what I thought I knew.
I lost a lot of things, 'fore you came
I know that losing is just part of the game
And I'm sure I'll lose more, but all the same
It ain't what I lost that makes me sad
It's what I thought I had.
Well it is what it is, let it go
It ain't what it was, that's for sure
Things will be what they'll be
In spite of me or you
Even though
It ain't what it is that's such a sin
It's what it might have been.
Oh, it is what it is, let it go
It ain't what it was, now we know
Things will be what they'll be
In spite of me or you
Even though
It ain't what it is that's such a sin
It's what it might have been.
