The only one I actually remember was from when I was a kid, and it felt weird and awkward because my dad was an elder. They even acted awkward, and I remember it being said the only reason they were there was because the C.O. had been on their case about making sheparding calls to all. (Actually our congregation was real bad about making ANY!) They were like "... well, this was swell. Next week, you can come see us! Haha!" Talking to my dad.
As a young adult trying to fade, I remember them trying to make an unscheduled sheparding call. I hid. I'm not ashamed of it! Self preservation. We've all done it! :)
