I remember in July 1975 when I was 11 my mother booked a flight to Italy with her 3 kids to visit her family which lived in a small town, that is to say my grandparents, uncles, aunts and cousins. Her intention was to try to "save" them, by letting them know that the time was very limited and that the Governing Body the Bible was teaching that the big "A" was coming in a few months. Needless to say no one listed to her (good for them!).
When we went back in 1981 we heard an earful and got some taunting (rightly so) from family members. My mother was all defensive saying that God delayed judgement to give people a chance to listen to the good news as preached by the Witnesses be saved! But that didn't stop her from getting into arguments over the Bible with my aunt who was a nun. A priest even came over to talk to my mother (now that I think about it, it was almost an exorcism!).
Thankfully non of those family members became witnesses.
