Remember that responsibility means “the ability to respond.” When we’re responsible we don’t necessarily fix or take care of things, we respond appropriately. ~ Covington, Stephanie S. A Woman’s Way through the Twelve Steps (p. 154). Hazelden Publishing. Kindle Edition.

Who would have realized the words
responsibility and sponsor are related?
The Online Etymology Dictionary
declares the origin of responsibility:
1590s, “answerable” (to another,
for something), from obsolete French responsible
(13c … as if from Latin *responsabilis),
from Latin respons-,
past-participle stem of respondere
“respond, answer to, promise in return,”
from re- “back” … spondere “to pledge”
(see sponsor (n.)). Looking at sponsor
you end up with “give assurance,
promise solemnly.”
To take responsibility does not mean
it’s all on your shoulders now
but that you’ll do your part,
to decline to ignore, to act appropriately.
Is that not what both Sponsor and Sponsee
should do? You need not remake the wheel,
just do your part and be honest about it.
Respond Appropriately.
