I also noted the "evidently" single sister aged about 50 who was obviously supporting herself and studying hard and using her DiY skills to help the older sister.
I could not help but feel sad for her even though she is a Watchtower construct. I imagined her as a young woman, pioneering in the 1980's assuredly telling folk that this system wouldn't last beyond the generation that saw 1914.
I imagined her in her 30's doubling down when the generation definition started to change in 1995 and she put off having children and marriage because she could do those things in paradise.
Then her 40's when thoughts of "where else would I go" might be suppressed. And now in her 50's making the best of a menial job and plodding round houses on the ministry studying with mental cases to parade her deluded beliefs as a cure-all.
But maybe that is just my construct?
