Once, in a rainstorm, I witnessed the creation of a rivulet. The water had come down, the stream had begun in a hollow of earth the size of a leaf. Then it filled and began to flow. The rivulet rolled down the hill between some stalks of grass and weed, it moved in spurts, down the fall of a ledge, down to a brook. It did not know it was not a river.
