Maybe in this case. Though what the heck parents are thinking sending their kids up there is beyond me...
I suppose they're thinking that the experience will be valuable to them in college or adult life - a "check in the box" that sets one college applicant or job applicant apart from others.
Perhaps they don't think about their teenage children, especially boys, being sexual prey for adults. Or they think their child has too much sense to be a victim, not understanding the dynamic involved with a powerful adult figure, a young person away from home, etc.
Anyway, my first instinct would be to attribute positive motives to a parent. A few years ago, I might not have thought about all the possibilities, myself!
