Ancillary- "One who assists or serves another".
Sounds like a slave or an indentured servant.
Is that what it means or is it like a helper
free to make your own decisions, help as you desire?
I think not, it means one who is a slave
and can't leave the dullness or hardship
of being with the same person
every second, every minute, every hour, every day, every week, every month and every year
'til both of you are no longer living.
