A sad story. After my Dad died Mom slipped into dementia (neither were every JW's).
It is really hard to watch smart loving people slip away like that. I am very fortunate that I was able to be there for both of them.
Words fail me when it comes to the attitude of witnesses toward things like this. The lack of compassion speaks volumes about what their religion does to people.
Any chance you can talk him into giving the 30% to a real charity and not the WTBS?
