I stood on a ledge. I looked over it, trying to see if it was safe to jump. It obviously wasn't. I was high enough that if I tried to jump I'd end up like a pancake. I looked behind me, at the narrow staircase. Being a pancake might be better than what might come pouring out. I looked down again, looking for a way to climb. A way to survive. Suddenly I felt something slam against my legs. They crumpled. At first, I thought I'd land on rock and get knocked out. Then I remembered there was no rock in front of me. I was tumbling through the air, towards the river that meant certain death.
