I was the Theocratic Ministry School Overseer for 14 years. I would get so frustrated with how frequently people would fail to show up for assignments which they voluntarily agreed to take. That and last minute cancellations were the bane of conducting the TMS. The only thing worse was scheduling the Public Talks—which I also did—for the same reasons.
And, yes, I was always prepared to handle every part in the event it was necessary. What a stressful responsibility. So glad I don’t have to worry about that nonsense anymore.
