DaF stated "CO visit is like a motivational speaker seminar"
I am not sure I ever experienced a CO visit as a motivational speaker seminar. I think it is more like an IRS audit or tooth canal. A tooth canal is probably overstating. But it is definitely an audit. He fills out a report about the congregation that is sent back to HQ. If that is not an audit, I am not sure what is.
In any event, the week wreaks of coercive power over the flock.
Which probably explains why your wife is so on edge around the CO visit week.
