It's 6:42 in the morning. It's completely dark out. I'm outside, getting the garbage out to the curb. Suddenly I'm started by a teenager trudging slowly up the sidewalk. She's followed by several others. All are wearing iPods. None acknowledge my presence. I make some noise with the garbage cans in hopes of not startling them, but I realize it does not matter. These children are not alive. They are early morning teenage zombies. It's like a George Romero film. I wonder if I could sneak up behind one of them and tip him over.
