I can say that some elders never want to make shepherding calls, whether just to encourage and especially not if there is a problem. There were elders that wanted sincerely to help but could not find another elder to go with them.
One energetic brother was like a poster here described, working in field service with the people in his group, making a social visit on every family every six months. He was pulled aside by 2 elders and was told he was making them look bad. That the other groups expected the same attention and they were too busy golfing and snowmobiling.
I saw 2 elders burn out running around trying to help all those who needed help while the other 5 elders let them. Their families suffered as well.
I personally always had a pet peeve. Elders who dropped by unannounced who did not call and check what time was convenient for you and then were surprised when I did not invite them in. Rude, rude, rude!
