Hey truman :
Did the incident you mention by any chance happen in Nesbit, MS sometime in the late 80's or early 90's? I don't remember when, but the exact same thing happened one Sunday when I was there. As it happened, the speaker's fleshly brother was the one who stepped up and finished the talk from the outline. Did a pretty good job, too.
In this case, however, the sick one DID get attention and was treated with loving concern by several elders and others. And his brother, who finished the talk for him, is actually very nice and humble and unassuming. Not one to put on airs at all. I know there are plenty of "showboats" among the dubs, and I have seen plenty of cases of callousness and lack of concern for others, especially for those of the "lower" classes. But in this specific incident, everything was as it should have been.
Just goes to show that even though the Organization is legalistic cult seeking to contol even the minutiae of its subjects' lives , individual Witnesses can be as sincere, thoughtful, and loving as anyone else. Even the all-powerful Borg can't stomp out the decency in every single one...
