LisaRose asked if they shortened the meeting by 15 min. or fill in with "more meeting". As far as I can remember the attempt was to keep the meeting to two hours but at first HQ was not clear that the 2 hours INCLUDED the songs and prayers which often added as much as 10-20min.
I remember my FIL at the time was the WT conductor. He would get steamed if the public speaker went overtime bc it meant he would have to shorten the WT study-sometimes dispensing with reading some of the paragraphs. Which reminds me, were read AFTER the QandAs. Can't remember when it was changed to reading the paragraphs before. He sometimes and told the cong that "We will have to move on to the next paragraph (without reading) because our study has been cut short. (By the speaker). LOL
