Water and war

The man in this story is living with a very odd houseguest. He doesn't mind, however, and in fact finds his visitor quite agreeable. They talk of many things, the man attempting to explain his way of life to his curious guest. But when it comes to the subject of his people's wars, the man completely confounds his visitor. And in the end, the man is left with only one choice, which is really no choice at all. This story is a tribute to the late, great Ray Bradbury.
