When I was a kid I would occasionally spend the night at a friend’s house and play “ninja.” We would dress up in all black and sneak out of the apartment building after his parents fell asleep. We didn’t do much besides see how far we could travel by staying in the shadows and try to identify sounds that we heard in the distance. Then one day we got lost working our way through the neighborhood to try and find a friend’s house. We walked out into an intersection to get our bearings and were standing under a street light as the police car drove up.
