How to break a heart (poem)

How to break a heart
It is not difficult
Anyone can do it
So could you, if you tried
Just find a light
And switch it off
As easy as blinking
That's what I was taught
When I was too young to ask
By ladies in white nightgowns
In dripping weeds and black ribbons
A girl's best friend is a small handgun
The question was useless
For I could say yes
But you've got to ask my army
And they are not inclined to grant favours just now
