The best place for writing poetry is sit by a river.
especially when leaving a loved one,
if you know she’ll go back there eventually,
in some week, in a month, or a year,  you would be able
to write with a loudest mind
but you must
know you’ll never see her,
and so it’ll be merely a monologue

Begin the poem with separation,
writing,
selflessly giving it everything in you
out of selfishness, out of need for sympathy.
