So my wife has started going to Sunday meetings again. When she returns home I ask her what she learned.
Yesterday's talk was about "putting up with brothers and sisters who suffer depression" (in my wife's words). This confirms my suspicions that there's a high percentage of JWs who suffer from depression disorders. In my opinion living as a JW possibly causes depression.
This is worth a read. It almost perfectly describes the behaviour of most Jehovah's Witnesses I've known.
