dazzle of white teeth that was all the brighter in his bronze face. "If I'm bursting with anything, sir, it's just plain nosiness." Jerry glanced from Ollie to the wall clock—spaceship clocks were always set at Eastern Standard Earth Time—and sighed. He was cutting it terribly close this time. Suddenly, he wanted very much to have someone to talk to. It didn't matter, all at once, that he'd be exposing himself to danger by relaxing his mental grip on himself. If the ship were not landed and his job begun within two hours he'd be no worse off speaking than if he'd kept still. "Sit down, Ollie," he said abruptly. The mess boy's eyebrows rose at this unheard-of request, but he perched obediently in a chair, almost poised for flight on the edge of the seat. To have a chat with a Space Zoologist was without precedent in Ollie's experience. Jerry carefully poured himself a cup of coffee, took a sip and settled back comfortably in his chair. "What's on your mind, Ollie?" "Like I said, sir, just plain nosiness. I—I can't get over you Learners, sir, that's all. I always wonder what gets you into the business. Why you stay in it so long, why you die so quick if you quit the Corps, or—Well, like that, sir." "Just general curiosity about my raison d'être, huh?" said Jerry. He wasn't trying to floor the mess boy with a four-dollar word; even the lowliest crewman on a spaceship had been chosen for brainpower, long before brawn came into consideration at all. "That's about it, sir." Ollie nodded. "I mean, I watch you, sir, when you come out on these trips. You get all keyed up and worried and sick-looking, and I keep wondering, 'Why does he do it? Why doesn't he get out of it if it affects him like that?'" Jerry stared ruefully at the wall before him, and didn't meet the mess boy's eyes as he replied. "Every man gets keyed up and scared when he has an important undertaking at hand. It's just worry, plain and simple. The thought of failure keeps me all tightened up." Jerry paused, awaiting a response. When none was forthcoming, he turned his gaze slowly to meet that of the mess boy, hoping he was doing it casually enough to allay anything like suspicion in the other man. But the smile he met was, affectionately, the smile of a man who hasn't been fooled.
