Human: Compose a first person description of a suspenseful scene outside a sink hole with water, a skeleton, and a cenote. Assistant: 
You are standing on the edge of a deep sinkhole, about eighty feet wide and perfectly round. Peering into the deep hole, you find that it's filled with water, the surface about thirty feet below you. Judging from the smoothness of the walls and a skeleton still clinging to the rocks below, you surmise that jumping into this cenote might be a bad idea.
