Look at them...
maybe they're already dead...

Jim sits above the overpass. 
He balances there for hours.
He likes watching the cars go by. 
He wonders where they're going and about their lives.

He wonders how many will be in accidents that night.
He wonders if he's ever seen these cars go by before.

He loves the cars. He lives through them. 
Jim needs those cars. They keep him alive.
