The Only Thing I Know

I'm living with your memory
In the attic in my mind
And you've been getting by without me
But I've been spending all my time
With a girl that I remember
Who'll never leave or need to grow
'cause when you left you left your memory
Now it's the only thing I know
When the past gives me no comfort
And though the future is the cost
The way I'm choosing to remember
I'll forever be the man I never was
And you, you fade
But the memory remains the same
And I, I can't change
And I think that living with your memory
Is slowly driving me insane
You are perfect but you're empty
