The last few years I was still serving as an elder I began to edit my assignments. First I just left out things I had doubts about or disagreed with. Then I went through all my Public Talk outlines and culled the ones that even dealt with subjects I couldn't endorse. I asked the Talk Coordinator for a couple of new outlines telling him I wanted to "freshen up" my talks. I picked subjects which were non-controversial (to me). Then I told him I would no longer be giving this talk or that.
The first talks I dumped were the ones that dealt with End Times predictions and Last Days prophecies, such as the Seven Times of Daniel or the Time of the Gentiles. Really I only gave talks on subjects like "Appreciating the Marvels of God's Creation" or topics dealing with developing Christian qualities. Ironically, I only recently realized that these were the things that interested me and in which I believed BEFORE I became a JW!
I made similar changes in my TMS/SM parts and of course only commented at the WT or Bookstudy accordingly.
Now to me, this is the truly amazing thing: No one seemed to notice! Not my wife, not my kids, not my fellow elders or anyone else, no one seemed to notice the changes.
If anyone did notice, they never said anything.
