An interesting article from the Star Tribune on confronting runaway children, particularly Hmong girls, who apparently, in many instances, keep going to classes even if they don't go home at night.
Unfortunately, there's also a high probability of rape and encounters with gang culture while they're runaways.
It's not a perfect article- it's particularly light on man-on-the-street reactions from non-pundits who are Hmong, for example, but I suppose sometimes you just have to work with what you can get.
Some parts remind me of old Ed Buell's remarks decades ago in Laos, though. He said that anyone who was speaking English and telling you about the problem didn't understand what the real problem was.
