Sea Legs

I'm standing on a waterbed
Balancing my composure and my weight
Practicing my lines and my poker face
You taught me a fortune's worth of patience
But destroyed me with continual maintenance
There is an onslaught of weapons
Tucked away inside your coat
I wish it were me and not you
But it's not, so cut me to ribbons
Blow holes through my chest
Dismantle my bones and burn whatever's left
Break my sea legs and let me sink in
