I'm about your age, Phoebe, so got the same lecture from my Dad, but I knew that the Ancient Worthies hadn't shown up in 1925 so their track record wasn't squeaky clean. I also knew that leaving without getting shunned was unlikely so baptism didn't look all that inviting.
Deciding to get baptised was the best decision I never made. I'm not shunned by any JW family members. Relationships are stunted and are not what they should be and I'm careful what I say around them but, because I'm unbaptised, I do have some semblance of a normal relationship with my JW family and old JW friends even though I haven't been in a KH except for weddings and funerals since the 1975 debacle.
