Born in 1970, 4th generation jw, remember some family discussions about the "excuse" watchtower article in 1979. It was a family debate. Later I heard we missed a summer holiday in 1975 because of the predictions.
In 1985 I asked my father about the big boxes with rice at the upper floor level. Hé told me because of 1975, but only a mouse had advantage of it.
It is still strange that dad says hé never believed in 1975 but sold his house, and went pioneer that year.
Later hé changed and became a jw with a succesfull public life.
