Cath,
I don't know how to find it anywhere but I think my JW aunt heard about it 40 years or so ago.
I had a cousin who was about 11 at the time, she loved her long blond hair. She spent time taking care of it. I guess she spent too much time looking at it in the mirror and didn't do something she was suppose to do because one day my aunt dragged her by it and took sissors and hacked it all off very short saying it was a sin to love herself that she was conceited. It broke my cousins heart.
It took me many years to even start to forgive my aunt for all the mean things she did to me and my cousins. I thought of her as a Witch. She was a strong JW, but a horrible person.
