"I can't point. Anyway I don't know," said Docchi. "I can get it for you on the scanner." Jeriann laughed. "Never mind. I don't need to see their planet. They'll come soon enough." "Almost too soon. I keep wondering what they're actually like." "Me, too," said Jeriann. "I don't even know how big they are. Sure, I saw them on the screen for a short time, but it's not like meeting them. Large butterflies is what I first thought, but the resemblance fades as you continue looking. And, what is their size? There was nothing familiar to judge them against." "Wingspread is a better measure," said Docchi. "The general said eight feet but I think he was overly impressed by the flat expanse of their bodies." In a while he added thoughtfully: "But it was not their height I was thinking of." "I know," said Jeriann. She frowned. "Why did they choose us? They could have had the general's expedition. Instead they asked for us. Why?" They went on in silence, past the acid tank. They looked in. It was empty. Now they had better use for the chemicals. "How is this for a reason?" said Jeriann as they strolled away. "Still on the aliens?" "Why not? We've got to learn how they think." Docchi smiled and through the darkness she could see the faint luminosity of his lips and where his eyes crinkled. "We do, but in the absence of anything positive all I can apply is self-interest. And I don't see how they benefit by having us." "I do," said Jeriann. "It's because we're normal." She hurried on before Docchi could protest. "Don't try to talk me down until I explain. When they contacted us yesterday and said they'd be here in about three weeks, on an official visit, did you notice which one was prettiest?" "I figured that much out myself," said Docchi. "At least in the beginning we look very much alike to them, as they do to us. Appearance doesn't count." "True, but that was not my point. I haven't reached it. When you looked at the--uh--butterfly that spoke to you in that high squeaky voice you were wondering how he learned our language so well in such a short time. You were thinking: are they all as smart? Can I trust him?" "We've got to trust them," said Docchi grimly. "We're a long way from support. And they did ask us to stay." "But trust all of them, every individual butterfly, under any circumstance? Or just some?" "We're dealing with a government," said Docchi. "We aren't concerned with individuals. There must be deviations in what they're like. Some won't be trustworthy." He paused. "But of course a government is a reflection of what its citizens are." He paused again, came to a dead stop. "And so, for the aliens, we are average humans." "That's what I meant," said Jeriann. "A _cross section_ of what they'd find on Earth. But of course they can't go to Earth and see for themselves--not yet. And so they had to make the best choice of what was at hand."
