I was studying in 1985, when concerned friends and relatives brought up the 1975 predictions, of which I was unaware, I asked the young couple studying with me, and they gave me the standard answer "Oh, some Witnesses thought that...but the 'Society' never said..." Of course they were just repeating what they had been told. Had I been alert I might have asked "But I thought you all spoke in agreement! Why would they think that?" But I didn't, and when I pressed for more information they gave some goofy reply about "We don't know how long Adam was in the Garden of Eden before Eve was created"
Our Kingdom Hall had an extensive library, so researching myself, I saw the statements that were made in Watchtowers, but it was so far removed from where I was mentally at that time that I was puzzled but it didn't really impact me. Some time later, the older brother who conducted the then-in-private-homes Group Book Study, and liked to reminisce, recalled a Convention where "...Brother _______(I've forgotten the name...)...really made it sound like it was 'comin' that year.."
Later when I heard that some had bought cars, gone into debt, thinking they'd never have to repay, I was extremely puzzled, because the brother who first studied with me, though young, was very severe, and had heavily emphasized that we were to be NO part of the world, it, and its Religious, Political, and Commercial systems were passing away, and if we were tied into it, in any way, we would pass away along with it. This led me to believe (for a time) that we should not own property, have insurance, or debt. Later, reality set in...
As many others have proved amply, much was printed and said to raise, promote, and encourage expectations. And there used to be that blurb in the magazines about "a peacerul new world, sure to come, before the generation thst saw the events of 1914, passes away..
