Interesting that you mentioned this.
Yesterday I went back to the kingdom hall (different congregation) after some years because I was told that a long time childhood friend would be giving the talk and this sister - a long time grandmother figure for me - just knew what buttons to push so I gave in and said I'd visit. LOL
Turns out it was someone with a similar name so it wasn't him. We were all disappointed. But that's not the end of it. The speaker was so boring and parrotish using all typical clichés and shallow reasonings that I was starting to feel embarrassed FOR HIM! LOL All he needed to do to make himself look worse was to pick his nose on stage -- which he finally did at the end of his talk.
Not a total loss -- the entertainment value was worth it.
But what I noticed was the attendance -- not even half the hall was filled.
That was interesting. So maybe there is something with this book?
