This experience illustrates that people don't matter much at all to Jehovh's Witnesses. The only thing that does matter is the Organization; making the Society grow, making it look good, making it prosper, delivering it's literature, spreading it's message.
No one noticed this woman's situation beause the minds, activities, and pursuits of Jehovah's Witnesses are full of Organizational concerns. People are simply stepping stones, used to the end of making the Organization succeed. When they are no longer useful, they are quickly forgotten.
Love of God and neighbor? Neither are seen much in this religion. It's truly sad.
