Those are silly questions. I would've expected better from you, crash.
I was 16 once. In recent years I've known four or five 16-year-olds pretty well, and I have a nephew who will be 16 in just a few months. Neither I nor any of these others was so immature at that age that we could have possibly been scarred by an unwanted sexual advance from some old lecher like Foley.
If, certainly by the age of 16 if not by the age of 2, parents have done nothing to prepare their kids for that sort of thing then as far as I'm concerned those parents are negligent. If those same parents sent such an unprepared and immature kid to live among other kids with a politician in loco parentis in a distant city, I'd call them criminally negligent.
None of this is meant to excuse what Foley did in any way. But all this caterwauling about those poor, damaged kids is just so much bullshit.
So it's really the parents fault?
Does anyone in your world have responsibility for daily actions?
