"That's all!" Slood's face swelled with emotion. "You can't really be that indifferent."
"Another job, that's all it is to me," Narli persisted. "At an exceptionally high salary, of course, or I wouldn't dream of accepting a position so inconveniently located."
Slood was baffled and hurt and outraged. "You have been honored by being the first of our people to be offered an exchange professorship on another planet," he said stiffly, "and you call it 'just another job.' Why, I would have given my right antenna to get it!"
Narli realized that he had again overstepped the invisible boundary between candor and tactlessness. He poked at the nuts with a stylus.
"Honored by being the first of our species to be offered a guinea-pigship," he murmured.
He had not considered this aspect of the matter before, but now that it occurred to him, he was probably right.
"Oh, I don't mind, really." He waved away the other's sudden commiseration. "You know I like being alone most of the time, so I won't find that uncomfortable. Students are students, whether they're Terrestrials or Saturnians. I suppose they'll laugh at me behind my back, but then even here, my students always did that."
He gave a hollow laugh and unobtrusively put out one of his hands for a nut. "At least on Earth I'll know why they're laughing."
There was pain on Slood's expressive face as he firmly removed the nut tray from his friend's reach. "I didn't think of it from that angle, Narli. Of course you're right. Human beings, from what I've read of them, are not noted for tolerance. It will be difficult, but I'm sure you'll be able to—" he choked on the kindly lie—"win them over."
Narli repressed a bitter laugh. Anyone less likely than he to win over a hostile alien species through sheer personal charm could hardly be found on Saturn. Narli Gzann had been chosen as first exchange professor between Saturn and Earth because of his academic reputation, not his personality. But although the choosers had probably not had that aspect of the matter in mind, the choice, he thought, was a wise one.
