An obvious one is the families that never miss a meeting and never miss arriving late with resultant fuss.
This for sure.
Many years ago my father, an elder at the time, told me how in the area he lived a family with six kids would always show up fifteen minutes late to the Sunday morning meeting. They complained about how difficult it was to get up and ready and be on time at 9:30 A.M.
So out of concern for them the elders decided to move the meeting time to 10:00 A.M. And that family was very consistent in showing up at 10:15 A.M.
