When they asked her if they could read her a Bible verse, she should have responded "Why?" instead of saying yes. "Why?" asks "What's in it for you?" and that's what needs to be understood to make a sound decision on whether to continue in a transaction (or relationship!)...not, "What's in it for me?" but "What's in it for you?" That simple "Why?" could have exposed the fact that JW's are there for their own benefit (saving their necks at Armageddon, not yours).
She also gave them 'wayyyyy too much personal information. What right do total strangers have to ask about someone's life and lifestyle? She lets two strangers in her house, then tells them exactly what she believes, how she lives, and how she is training her children? Why???
