This case reminds me of an experience Bro Lett related at a zone visit a few yrs back.
In it he told of a 10yr old witness girl who offered her teacher a bible study. The teacher
agreed but only if the girl came to the teacher's house one evening a week - alone!
The girl agreed and went along, the end result of this wasn't made clear that I remember,
but the girl of course was praised for her courage, other young ones were encouraged to
be the same.
I was outraged at the irresponsibility of this admonition.
Honestly my flabber had never been so ghasted!!
