Wow...you guys are like my soul mates. I'd actually forgotten this, but TOTALLY agree, and I used to be so bugged by it.
I don't mean to be overly harsh; I mean some of the people praying this way just picked it up from someone else and thought it was the right thing to do. But it just felt like a self-serving opportunity for someone to show you how attentive they'd been throughout the meeting/assembly/convention. I didn't think it was wrong to include (what seemed to be) a very important or timely point made during the meeting, but this lecturing with a laundry list of meeting topics did not seem directed at God--but directed at those with bowed heads.
"...and, Father, please help us to always remember the need to be diligent in all the alternative types of Witnessing today. In the shopping malls, in parking lots, over the phone. And help us to appreciate the significance of the seven-headed Wild Beast--and the meaning of all ten horns and ten diadems. And don't let us forget how hard our brothers are working to arrange discounts at hotels during the convention, and to appreciate what a slap-in-the-face it would be to go to the Holiday on Lincoln Avenue instead of the Holiday Inn on University Drive."
