there's a scene in "The Other Boleyn Girl" in which a pregnant woman takes to bed to insure a safe delivery.
altho it's hardly customary for me I have performd a variation of that with poem pangs. after all these decades I still have little comprehension of the birthing of poems. but recently something was happening that I knew wd be a poem. so I stretchd out on the couch & closd my eyes till it workd its way out.
