I turned in phony slips with minimal hours on them for a good 9 months. They were either late, or not in at all. After 3 slips with zeros on them the boys came for a shep call. They offered "encouragement" with the usual guilt, fear and obligation routine. I put them at ease without showing them my cards. I thanked them for their concern and for visiting my wife and I. Then I never handed in another slip. The CO visit is soon, so we will see if it comes up again with them.
Basically they don't want your low/no hour slips dragging down the cong average, but if you go inactive the CO will be all over them. If you can make it past the next CO visit you'll probably be fine. They may try to visit while he's in town or just before. This type of situation is discussed directly during the CO visit. The CO basically expects the local elders to make an effort to 'encourage' newly inactive ones. You may want to be "busy" around that time.
Are you on anyone's Apostadar? If it comes up that you've been "thinking" or "questioning" or "taking a step back to consider things" you can expect that the CO may lead a witch hunt on your ass. Just act discouraged and busy. Thank them for their concern, and maybe show up for a meeting or two after. Hell, throw your hand up in the WT study and read a scripture. They love that shit. Then back to good ol' inactivity.
Just remember... Once you hand in one slip, even with a zero on it... The process is started all over again.
