I think this is a wrong expectation that people in a congregation are going to care for anybody’s aged parents.
No offense taken. I agree with your comment, and perhaps the way I phrased "care" was misleading. Shortly before my mother died she was sitting at her front window watching passers-by and as it was just before 9:00 A.M. she would remark as a vehicle went by, "There goes bro. so-and-so to the meeting for service," or, "There goes sister so-and-so to the meeting for service." Then with a catch in her voice she said, "They go THAT way to the kingdom hall, and then they go the OTHER way home. But they NEVER stop here anymore! They JUST DON'T CARE!" My parents home was separated from the kingdom hall by only two residential homes.
So yes, while one should not expect that other people in a congregation are going to care FOR aged parents, those who profess to be the only true Christians who are identified by being the only ones on the whole earth who show Christ like love for fellow believers are IMO shown to be lying hypocrites when they willfully refuse to care ABOUT anyone who is aged, shut-in, or otherwise no longer one of the chosen few.
