When I find them in the morning, still asleep, with a device in their hands, the truth is, I have no idea where they have been or who they have been with all night.  It is like I am inviting the darkness of the streets into their own room—and the darkness is actually more aggressive than it has ever been.  All of the things my parents worried I might be exposed to if they let me stay out past 10 p.m. are a reality, and they are at my child’s fingertips.
