I'm asking what you would do to a 19-year-old who has sex with your 11-year-old. Have his parents talk to him like you advised me?
But let's say your daughter is also around the same age (a legal adult). What could you do then? Nothing, I'd imagine. Similarly, how do we know the kid (or kids) who received the drugs in this story were not also of legal age? If they were, we as parents really can't do shit about.
