I think it's someone who cares deeply, but is heavily indoctrinated and scared. They are probably from the KH where you last served expecting you to come in.
We are having a CO visit this week. His first talk was about having an odbedient heart, and then closed his talk with the Nov wt quote
"At that time, the life-saving direction that we receive from Jehovah’s organization may not appear practical from a human standpoint. All of us must be ready to obey any instructions we may receive, whether these appear sound from a strategic or human standpoint or not."
He said blah blah blah Armageddon is around the corner.......yawn yawn yawn........the UN this that and the other.....yadda yadda yadda (with a convincing and charasmatic CO voice)
So this person might be hyped up with renewed zeal and thinks you are going to die soon if you dont go to the KH, because you will prove to have a disobedient heart.
You are disobeying the GB and you need to listen, obey and be blessed!!!!!!
