Hi Jason - never being baptized was a good thing for you.
It could be your relatives getting the local elders to try and "help" you - what with the end being so close and all - or if they are from your old hall then they might be going through all the old record cards.
Typically the Secretary has a file with record cards - for baptised and unbaptised publishers - in it going back to the year dot.
So when someone drifts away/goes inactive/dips under the radar without judicial action then their record card will be put in the inactive section.
Every so often - the elders will go on "a drive" to reactivate and reach out to the "inactive ones." And of course they can count their time doing so.
This might be triggered by any or all of:
1. A relative (remembering the Return to Jehovah brochure) phones up and says "will you give Johnny a call?"
2. Annually they're supposed to call on the DF and DA to see if they have any thought to coming back and keen bodies of elders will occasionally add the "inactives" to that.
3. The CO's coming and this particular CO might tell them to have a go at reactivating the "inactives".
4. A bright keen spark on the body might decide to have a go at reactivating the "inactives."
5. They are trying to smoke out a "sinner" - usually only baptised ones but if they think you are contaminating the sheep they might go for an unbaptised publisher. In this case they turn up around hallowe'en looking for pumpkins on the porch or near Xmas looking for inflatable Santa or Xmas trees.
As an unbaptised publisher you shouldn't be treated the same as DF ones but of course some uber dubs love to shun!
