The future, thought Blurtso, doing his best to understand the idea. What could that be? Something that has not happened and is not happening and may not happen but will happen in a present that is not this present. Hmm, a present that is not this present. Where does this present end and the next present begin? If I found that point, would that be the future? Blurtso did not have a very big brain, but even he knew that such a point would never be found. There is only one present, he said with confidence, even I know that.
Here I go! said Blurtso, looking down at what lay below him. Here I go! he said again, still looking at all the things that lay below. Blurtso’s boney little hooves clung tightly to the rocky spine on which he stood, and his pin-point eyes were bright and full of frenzy. Here I go! he said a little more quietly, and with much less conviction. Here I go! Here I go! Here I go! he repeated, and clung even more tightly to the spine that began to cut into his hooves and make them bleed. Here I go! he said more loudly, but with no conviction at all. Here… I… and off he went, slipping, sliding, and tumbling into the only future that awaited him.
