The two Elders, unkown to each other, who showed me from the Bible that Jesus was God. Then would stand on the platform and say he wasn't.
The Elder who went on about how we shouldn't watch 18 rated films. Then one night his son showed me a cupboard full of them at his home.
The married Ministerial Servant aged 25, also a pioneer, who was held up as an example to the youth of the congregation. Then was discovered to be having affairs with three women on his window cleaning round. (not all at the same time)
The two JW brothers who were full time pioneers. They said they were going to share a two bed-roomed apartment together to keep their costs down. They lived together for about 4-5 years then it was discovered it may have been a two-bedroomed apartment, but they were only using the one bed!! Turned out they had been having gay sex with each other, since they were 15/16 now they were 28/29.
Then there were the brothers and sisters who were alcoholics, but it was kept quiet.
All this in my 25 years as a JW.
