caught in the low report of her laughter
i found my shoreline (sand for the keel);
she made no attempt to breed it into domesticity.


instead, full-throated, she thrilled away like a loon...


later, perhaps too long later,
i flew from her.
i blamed the laughter.
the fact that she could not evolve further.
