A Wigwam for a Goose's Bridle

I can write you
pretty prose
on demand or by request
(I’d like to think I’m reasonably artistic with words),
but not a poem. 
My poetry
is not party trick.
It is neither a performance
nor a product made-to-order.
It is a flash flood of raw emotion.
It is a cleansing fire. 
And you,
you should be careful what wishes you make.
