If you want to find out whether they consider you a Return Visit™ or not, you can use a sign like mine which is placed prominently next to my doorbell.
It simply says
Note that the sign does not rule out social visits from anyone, JWs included. If a JW sees that sign and decides not to call, you know that their intent is "preaching" and they're likely counting whatever time, RVs and placements they can squeeze out of the call.
I used to know Pioneers™ who would call on Inactive People™ in the Territory™ and ask to use the bathroom. That's it. And they counted the RV.
