more can be said for centripetal force
by others than by me, but perhaps this---
matters not the cause a ship can lose course,
or wherefrom comes destructive impulses
or how one's hello and goodbye kisses
are same while differs the staying exchange,
variables determine hits and misses
and wakes the choices that create our range.
if i were the earth now and you the moon
and i knew how our crests were once estranged
from warm-hearted oneness by some fortune,
you swirling outward and forever strange,
no time would i waste calculating how,
i'd say, 'good-bye love. what do i do now?'
