He looked up at me, nodded a greeting and laid the book down with a faint expression of regret on his doglike face. I found a chair and sat down silently. I wondered how he found time to read. My job with the BEE kept me busy every day of the 279-day year. And his, which was more important and exacting than mine, gave him time to read philosophy! I sighed. It was something I could never understand.

I waited for him to speak. As host, it was his duty to open the wall of silence which separated us.

"Greetings, friend Lanceford," Kron said. "My eyes are happy with the pleasure of beholding you." He spoke in the ancient Niobian formula of hospitality. But he made it sound as though he really meant it.

"It's a double joy to behold the face of my friend and to hear his voice," I replied in the same language. Then I switched to Confed for the business I had in mind. Their polite forms are far too clumsy and uncomfortable for business use; it takes half a day to get an idea across. "It seems as though I'm always coming to you with trouble," I began.

"What now?" Kron asked. "Every time I see you, I hope that we can relax and enjoy our friendship, but every time you are burdened. Are you Earthmen forever filled with troubles or does my world provoke them?" He smiled at me.

"A little of both, I suppose," I said.

Kron hummed—the Niobian equivalent of laughter. "I've been observing you Earthmen for the past twenty years, and I have yet to see one of you completely relaxed. You take yourselves much too seriously. After all, my friend, life is short at best. We should enjoy some of it. Now tell me your troubles, and perhaps there is no cause to worry."

"You're wrong, Kron. There is plenty of cause to worry. This can affect the well-being of everything on this world."

Kron's face sharpened into lines of interest. "Continue, friend Lanceford."

"It's those oysters the BIT sent you a few years ago. They're getting out of hand."
