Brothers assigned #2 talks have no work to do at all as far as I can see. If you're even a moderately good reader, you could look over it for about 2 minutes ahead of time.
When someone doesn't show up for the reading, and another brother fills in "short notice", there really isn't any noticeable change in the talk, or how it's read. In other words, just about anyone could do it.
And then the counselor has to come up with terms about how well the brother read it.........etc., etc., etc.
The commendation is pretty much identical every week for this part.
The sisters have to do extensive research on their parts, but the younger brothers who don't do the #4 assignments have got it very easy..........for most, it's about a 5 min. preparation time.
Is this how it's going in your cong.?
