Jefferson Parks finished his last bite of pie and pushed the plate away. "By then I didn't know quite what to do. I'd been prepared for almost anything excepting this. It was frightening. I tried to rationalize it, and then I quit trying. It wasn't that I attracted attention, or anything like that, quite the contrary. Nobody even looked at me, unless I said something to them. I began to look for things that were _different_, things that I could show them, and say, see, this proves that I'm telling the truth, look at it--" He looked up helplessly. "And what did you find?" "Nothing. Oh, little things, insignificant little things. Your calendars, for instance. Naturally, I couldn't understand your frame of reference. And the coinage, you stamp your coins; we don't. And cigarettes. We don't have any such thing as tobacco." The man gave a short laugh. "And your house dogs! We have little animals that look more like rabbits than poodles. But there was nothing any more significant than that. Absolutely nothing." "Except yourself," Morgan said. "Ah, yes. I thought that over carefully. I looked for differences, obvious ones. I couldn't find any. You can see that, just looking at me. So I searched for more subtle things. Skin texture, fingerprints, bone structure, body proportion. I still couldn't find anything. Then I went to a doctor." Morgan's eyebrows lifted. "Good," he said. Parks shrugged tiredly. "Not really. He examined me. He practically took me apart. I carefully refrained from saying anything about who I was or where I came from; just said I wanted a complete physical examination, and let him go to it. He was thorough, and when he finished he patted me on the back and said, 'Parks, you've got nothing to worry about. You're as fine, strapping a specimen of a healthy human being as I've ever seen.' And that was that." Parks laughed bitterly. "I guess I was supposed to be happy with the verdict, and instead I was ready to knock him down. It was idiotic, it defied reason, it was infuriating." Morgan nodded sourly. "Because you're not a human being," he said. "That's right. I'm not a human being at all." * * * * * "How did you happen to pick this planet, or this sun?" Morgan asked curiously. "There must have been a million others to choose from."
