I scrambled back to the sidewalk and started cramming everything into my pack. At least I tried to. But nothing wanted to go. Paint tubes squirted through my fingers; brushes got caught in the sidewalk cracks. My water bottle rolled away. And that's when I realized there was someone standing near the end of the wall. I looked up. My mouth went dry. It was a man with a baseball bat. "I thought I might find you here tonight," he said.
