The whole recent thing about elders being encouraged to "persuade" publishers to drop RVs if they are not "progressing" appropriately is very odd and, like a lot of things, contradictory.
On the one hand, the message has always been "we cannot read hearts" and "it's not for us to judge or presume when only Jehovah knows if the person is ready and worthy", etc. And in recent times, with softening of the teaching about whether God will destroy every non-JW at Armageddon or not, that message has in fact been repeated more.
BUT
At the same time, the Org keeps pushing the idea that publishers should not "waste time" with "unproductive" Bible studies and return visits, and they have even given supposed indicators of evidence whether someone is making sufficient "progress", including this checklist from a few years ago:
Before discontinuing a Bible study, seek Jehovah’s direction in prayer.
While taking into account the student’s age or other limitations, look for indications of meaningful progress.
- Does the person keep his appointments to study?
- Does he prepare for the study?
- Does he attend congregation meetings?
- Is he making changes in harmony with Bible principles?
- Does he share with others what he is learning?
- Is he withdrawing from false religion?
In countries where JWs are being approached by many to have Bible studies I can perhaps understand this (allegedly, this is the case in some parts of Africa and South America, for example), but for most of the world I would imagine this is counterproductive to the ministry of most JWs. They have to make all of these assessments, potentially asking intrusive questions to do so, and at the end of it, might just drop an interested person leaving them hanging if they are not making what the Org deems the right "progress"!
That's when it emerged that one of the ladies from a previous visit had apparently said something about me being aggressive and argumentative. So it seems that they do keep some sort of record about what the households are like, if only a mental note.
Ah yes, well even though JWs have been sternly ordered NOT to keep any written records of their ministry now (at least in the UK and Europe - I don't know about elsewhere in the world), we all know that the Kingdom Hall is a perfect place for discussion of who lives where, what they're like and so on, and that applies to people met on the ministry just as much as fellow JWs! You're probably right that as a "brother" and one who needs to "get his hours in", he was probably either persuaded, or agreed, to take you on!
Bottom line is, if you want to make sure you DON'T become a "return visit" for longer than you're comfortable with, make sure you DON'T give that pioneer enough to say "Yes" to all of those checklist questions!
In all seriousness, just be straight with him. If you're happy to discuss Bible topics with him but don't want a study or anything more, say so. If you're happy to even study with him, but you will not take it any further, say so. Then let him make the call, but if he tries to push you beyond what you've agreed to, just draw the line and remind him, and stop it if and when you're ready.
I've always preferred that open approach with my return visits, and I respect when they can (politely) tell me "no thanks" or "that's enough", so I can move on and neither of us wastes each other's time!
