I think you gave your sponsee the greatest gift you ever could.
You showed her we don't have to be and are not perfect in recovery.
Of course, as a sponsor I have made mistakes, and have missed an important event for a sponsee now and then. I am human. Most times in my recovery, I have kept commitments I have committed to, however, sometimes things just do not go the way we plan them. That too is part of life.
You did good. You made your amends, your sponsee seems happy, so maybe it's now time to give it to HP and get on with today.
