The individual JW's are basically good people and yes, I both was the recipient of help with food during hard times and also returned the kindness to others. It was sometimes an announcement made at the service meeting back in the day...I do wonder if that would be allowed now. Mostly it was the 'sisters' that thought of and arranged such things. I remember helping out the family of one of our elders who had ALS. It was the sisters that did ALL the helping. Those of us who helped were taught to 'bag' the patient (compressing a bellows to give air to the patient) and suction mucous from his airway...something I never thought I could do but learned to do it. I was able to suction and make small talk over the Jeopardy game on TV without missing a beat at one point. I am glad I was able to help in this way but it was during a particular day that everyone was at a memorial service for another elder that I had a situation where the ALS brother needed to use the potty and he had weakened to a point that I couldn't hold him up. I kept him discreetly covered but still...it was just a terrible situation. I called the Kingdom Hall where the memorial was being held and asked for emergency assistance! Another elder was dispatched and he was absolutely....horrified....ashamed.....I don't know what but he was totally unaware that the sisters were doing all this caregiving and none of the brothers had offered any help whatsoever. The ALS brother died not too long after....
My experience with individual witnesses is that they are caring people but the corporate nature of the Watchtoer society gets in the way of natural affection.
