I was in the hallway, making my rounds. Every day for as long as I could remember, I would start at the end of the hallway and knock on every door, excluding the one at the very end of the hallway, in the center. The cracks under each of the doors that I knocked on revealed no source of light, but I prided myself in standing tall in the darkness. Outwardly, I was strong, I was tough, and I was threatening. But inwardly, I was no more than a black hole.
