Confession, I know where you're coming from in regard to giving speech cousel. I assisted in the School for several years before becoming Schoolmaster Overseer (), and yes, it was very tough giving a W, especially on things like personal appearance. I'd get quite nervous, and often had no idea of what I'd actually end of giving out even as I made my way to the platform.
I also noticed that the worst offenders in the area of Timing were elders. The Bible Highlights part almost always ended up running very long, and the Instruction Talk was a problem as well. Not being able to ding a little bell, tap a pencil, or otherwise stop the talk, I felt pretty helpless as I then had to rush the rest of the School because one or two elders couldn't shut the heck up.
