There was a sweet old brother in the first congregation I attended. I didn't know him well, but he seemed like a kindly soul. After I moved away, one of my (rebellious) JW friends wrote me a letter during the WT study and referred to the anointed gentleman, explaining that he was making his "Cedar Point comment," so the study was just about over. When he died, my mom (not a JW at the time) went to his funeral. She told me that our CO (a very sweet man who died at a young age) began the funeral service by saying, "On [date] a new spirit son was born in heaven, and the attendants at [his nursing home] sand that [his name] had died."
In my next congregation, there was another sweet, elderly anointed brother living in the Veterans' Home. My husband and I always gave him a ride to the meetings. I didn't notice anything strange about him except one time when he told us that the veterans' home was playing kingdom melodies through their Muzak system.
There was another slightly elderly brother who was on a health food kick.
There was one sister from a foreign country who was middle-aged. I didn't know her very well, but she seemed nice and normal. Once my daughter, at about age 5, asked how she was going to get to heaven. I don't remember how we answered that question.
