Brings back memories of a man that a sister had called on in field service. She was very enthused about his interest in our message and he was ready for a Home BS. She came to me because I had met 'Harvey' in a backcall with her and she wanted me to take on the BS. I did. Turned out he agreed with everything and wanted all the publications he could get. I picked him up for meetings and we had him over for dinner. He lived in a modest little house about 2 miles from where we lived. Every so often he would just show up, having walked over.
(Cut to the chase, Gregor!)
OK, so he turned out to be a savant. His specialty were dates, weather of the day on that date and could name the date of the second wednesday in January ten years ago.
Finally, one day, It was at his house for our BS. He took me into a back room to show me his "library". He had rows of the Watchtowers brightly colored books. All lined up by color. Like, 15 "Truth" books (dark blue) so on and so forth. At least a dozen pristine copies of every release for the last 10 years. He was very pleased with his rainbow. He hadn't learned shit from any of our efforts. I dropped him like a hot potato.
