How Can That Be?

I can't live without your breath
You are all that I adore
I'd say if you were the sun, I'd be the rays
But I don't think that's a suitable metaphor me
How can that be?
I don't know much but I know what I'm talkin' 'bout
I don't care about them anymore
I'd say if you were a kitty, I'd be the litter
But I don't think that's a suitable metaphor me
How can that be?
Enough talk learn to be subtle
Better ways of leaving than slamming the door
I'd say if you were the room I'd be the window
But I don't think that's a suitable metaphor me
How can that be?
