That Took So Long to Figure Out

"Well, you say that I treat you 
Like a book on a shelf
I don't take you out that often
Because I know that I completed you
And that's why you are here
That's the reason you stay here
How awful that must feel

You said you'd be my dream
I could have you every night
And if by morning I'd forgotten you
Well, no big deal, that'd be all right
Because you're the reoccuring kind
You are the reoccuring kind
You never really leave my mind

Are you the love of my lifetime
Because there's been times I've had my doubts"
