After a warm day, a cool night, only a few stars glowing faintly through a canopy of cloud, and the scent of dewy grass filling the air. The half moon has long since set. In the stillness, a single frog croaks a few times, then falls silent. A brief rustling in the dried leaves never cleaned from under the hedge at the side of the yard. One bark from a dog in the muffled distance. I can picture the familiar scene which I know lies around me, but, unseen, it might be anywhere, any world which my imagination could conjure. How little it takes to bestir those chemicals in my brain, and fill me with delight! Just lucky, I guess.
