I grip the fence with my fingers and I remember a picture my friend used to have. It was of a guy crossing over a road, and there was a fence surrounding it. The caption read: "without it, you'd be dead".
The cars all look pretty much the same from here. There are two categories; Coming and Going.
I call and ask everyone the question of the day.
"What are you living for?" I ask my best friend.
"I'm not sure. Just out of habit, I guess."
I move off the overpass.
"What am I living for?"
"The same thing."
I walk back to the center and grip the fence with my fingers again, forehead against the wire.
Without it, I think, you'd be dead.
