I had left the JWs 11 years earlier so it didn't have any effect on me. However, being curious about how the JWs were taking it, I attended the Watchtower Study at a congregation in Sacramento, CA a month before they were scheduled to study the Generation article. Surprisingly the KH was so full that I had to sit in the room used for the second school. I thought it might be the week of the CO's visit. But no, it was just a regular public talk and Watchtower Study. After the meeting I got a copy of the Generation Watchtower and took it home for closer study. A month or so later I attended the same congregation to see how the JWs would respond to the "new light," as it was the weekend for the Generation study. This time I had not problem finding a seat. In fact the attendance was only a third of what it had been during my previous visit. What was also interesting is how few commented during the Watchtower study. Also nobody said anything about this being a new understanding about the generation.
I thought that the low meeting attendance for that important study article may have been due to the fact that it was early December and maybe a lot of the JWs were doing their Chistmas shopping.
