I remember that cooling off period too, large gatherings were frowned upon and big gettogethers were poo pooed from the platform.
I also remember in the late 80's the visiting CO telling us off as a congregation because we had a problem with love and because we didn't do anything as a congregation any more. There was a lot of mumbling afterwards because we'd been told to cut all that out and were now being told to do it again.
Personally I think it just helped to create little cliques within the congregation. Family "clans" prayed and played together and everyone else was ignored.
