I was floating in the pool, trying to trace Orion with my little fingernail, but something wasn&rsquot right. The stars were twinkling a little too much and there were simply too many of them moving around. The pitter-patter of Marshall&rsquos paws on the wet ground soon drew my attention away from the dancing sky to the wagging tail, when suddenly, the lights went out. And there they were, hundreds or thousands of them, on every bush and every tree. Fireflies.
