When I was on the school I used it as an opportunity to "counsel" (with tact) the elders and those idiots in the congregation who thought they were more righteous than anyone else. The #2 talk allowed me to shape the introductions and closings of the talk. The #4 talks were a free for all. I only got one "work" while I was on the school from my "fleshly" brother who was the school overseer. It was my last talk on the school before I was appointed an MS. The introduction and closing of that talk was based on Wizard of Oz characters (Dorthy,Scarecrow, Tinman and Lion). Ooops. I actually had quite a few in the congregation applaude even though you weren't suppose to because it wasn't my first talk.
I became inactive...came back at a different congregation and gave a #2 talk to make another "point".Left that congregation after being cheated by a "brother" I worked for. I came back to my "home" congregation and gave one last #2 ( now it's just read the scriptures no introductions or closing remarks), but still managed to make a "point". The scriptures I got to read were Job 7:1-21 it was perfect for my situation at the time, because I got to emphasize the scriptures I wanted to stand out in everyone's minds.
Is it another hoop? Sure it is, but it can be used to your advantage. Becoming an MS is just an ego trip for most and an awakening to those who think it will aid them to "change" the cold-hearted elders dealings with the lowly ones within the congregation. It ain't going to happen. It took me 5 years as an MS to realize that.
