Whenever I would go to conventions, I thought it was weird how at the end of the brothers' talks (especially the older ones like from the Governing Body or whatever), they would start getting LOUDER AND LOUDER AND LOUDER.
ie; "in this time of the end, we need to KEEP ON THE WATCH FOR OUR ADVERSARY SATAN IS ROARING ABOUT LIKE A LION!!!! DO YOU AGREE??"
and then the audience would be forced to clap. I can't remember how many times at a convention the audience would have to show we "agree" with something by clapping on cue. It's okay once in a awhile, but not like 5 times a convention.
But, yeah the whole getting louder and louder at the end of their talks was always annoying and seemed like a technique you use on a child who has his hand in the cookie jar "You'd better not take that cookie or you'll be IN VERY BIG TROUBLE."
