It was a repeat of a repeat of a repeat.
I remember about ten years ago that Clyde decided to attend the book study that he hadn't been to for several months. They had just finished a study book, and it happened to be the night that they were reviewing the entire book. The conductor had some well-thought out questions, but most of the attendees sat there quiet--it was hard to answer questions on subjects they studied weeks earlier. Clyde just thumbed through the book and ended up answering most of the questions. Everyone was astounded--even myself. I asked him later how he did it--and he said everything is just a "repeat" of everything he ever knew.
