It's not just about what you see in this photo. It's about what you don't see. Whose bike is that? Where did he go? What's he doing inside that building? Why would he be doing that at such a young age? By putting the fence in focus in the foreground and leaving the bike out of focus, the viewer can't help but feel the lost soul who owns this bike is abandoning his childhood in favor of an unseen illicit activity inside that dark door.
