O my goodness, thanks for pointing this out dozy - I have to go to the meeting just to see this.
It is like a drama part at a Convention in form. Yet it is not a Convention, and it will be cringeworthy to say the least. I can't imagine anyone at our hall pulling it off with a straight face. Can't wait to see how it goes!
It does seem to me that Witness activities contain an inordinate amount of acting and role-play: the dramas, the sister's talks, the demonstrations. Witnesses are so well trained at how to put on an act, sometimes I think the acting spills over into real life.
On the stage, at a door, talking to school friends or work mates: it morphs into one - always feeling a bit like there is an audience evaluating the performance.
