I never knew any of them well enough to judge. They were figureheads who dropped in every once in a while and moved on.
With pity, I remember how the bros and sis would flutter around them as though they were celebrities. They would go way overboard to impress them--rehearsing their d2d presentations, making the perfect recipes for their lunches, using their best china, etc. They got so excited about it.
The bros and sis would hang on every word they said. For weeks afterwards, there would be retellings of what the CO or his wife said at the door or during dinner--every tiniest exchange would be analyzed and repeated.
Everyone would talk about their special recipes and whether the couple ate much of it. This info would be noted for next time, so their favorite meals could be provided.
I remember one CO said we can count our time while driving to the KH for the service meeting, and while taking multiple breaks in FS, "because Jehovah is kinder than human employers who don't give paid breaks". And then our tallies improved for years, because we were counting more time for FS even though we were sitting at Dunkin Donuts for our 2nd break of the morning (followed by lunch and a few afternoon breaks).
Wait a minute, if FS is so joyful and important...why do we need so many breaks...
Of course, official doctrine is they have no human leaders and do not follow personalities. Not true IRL.
