It's Only An Empty Drawer

On the face of it,
it's only an empty drawer.
Except it's not. It’s more than that.
It's her empty drawer, see?
It's remained vacant and unclaimed for over a year.
Until 30 seconds ago,
I'd clean forgotten about it's existence.
It's been hiding out in the corner of the bedroom.
Biding its time. Just waiting to pounce.
Before I know it, it's too late;
The weight of negative space
contained within
catches me an upper-cut to the glass-jaw.

Is that blood I can taste on my top-lip?
