Yep my mom started studying with the jws after they taught her that Christmas was a pagan holiday. Yep left a decent Christian church started studying with them and the world wide church of God. Both groups were teaching the end was going to come in 1975. My mom and dad denied they ever thought the end was going to come and this was being pushed in 75 but ironically my mom got her mother in the cult and she was baptised in the summer of 1975 .
I think the reality was that with her studying with two groups pushing the same message that she surely New about 1975 and was in a hurry to get her mom in. Then when nothing happened her memory just got all bad and she can't recall.
