Summoning the Devil

My school is right next to a mental institute. The only thing that separates the school is a fence with at least a 2 feet gap. Today during recess, my classmates and I were taking our usual walk around the school's backyard. Then a man in the basketball court of the institute caught our attention. He was standing in such a pose as if he was summoning something. You know, hands far from the sides, head up and eyes closed. Then he was talking...to no one. We couldn't hear exactly what he said. Out of the blues, he turned his head toward us. My heart stopped and my throat went dry. "Hello!" my classmate yelled. Surprisingly, he waved back. I was confused. So I ran without looking back.
