RILEY:
I consider the OP a little vague.
But, regarding your post it is really sad that those singles have only other Jehovah’s Witness to hang out with! In the real world this group would not be thrown together.
It is very unhealthy and stifling that JWs don’t bother with any other groups. (Is this majoring in a minor thing?) As someone not raised in the JWs I thought they were peculiar.
And a 9 year old is a child and should be with children in a similar age range. The most disturbing thing in your post is the 48 year old who never worked a day in his life. Not as uncommon as you might think in the JW religion - ‘mental issues’ or not. You don’t mention if this person is supported by their family. I would assume so.
All in all it’s an unhealthy situation.
