This, actually the whole hassle between Christine and her mother, is one perfect example why I am against putting too much pressure on people. It taints something that might otherwise have been a valuable concept. Ofc, you see people that still get used to their state or even (more or less) get to like their equipment, nonetheless. But the risk of putting people off and towards aversion is IMHO far greater. I don't want to accuse Christine's mother for bad motives regarding Christine or her chastity. Actually I rather want to believe she wanted the best. But you simply can't do it the way she did.
When I read humiliation, I read failure.
