Bow of my pains

Those arrows that impale you
Spring from the bow of my pains
If only I could pause my business
And sit like a tramp in the rain
To loosen that very taut string
Untangle the knots at its ends
To unravel and disarm the bow
Lay it peacefully powerless in the closet
So that never again can a stray arrow
Injure an unassuming and open heart
