"Yes, but what an ordeal," Tensor replied. His image took on the appearance of a relieved smile. "If it ever happens again—I don't know."

"It was that bad?" Curl showed suitable lazy civilized sympathy. "I was afraid. All that teleporting of yourself and things."

"It took me almost ten minutes to recover from it," Tensor said grimly.

"Tsk tsk. That's a lot of lactic acid to locate and destroy. But the Council will appreciate it, even if Prime did complain, poor fellow."

"Well, I promised to investigate and I'm a man of my thought. Of course, the curiosity vanished as soon as I got into actual communication with one of them."

"They communicate?" Curl permitted his image to appear mildly astonished, which was the only civilized thing to do. "Tell me about it."

"It's crude, but in some things successful," Tensor explained. "The alien I contacted was a female, for instance. When I adjusted for relative somatic sympathy so that I could stand the poor, uncivilized creature, I naturally acquired the full appetites of a male animal and this female seemed to understand some of my thoughts very well.

"You simply can't imagine the violent somatic compulsions one encounters under such a balance."

"Horrible," agreed Curl. "But I understand, my boy. I once fathered a child—must have been at least a couple of thousand years ago. Purely out of scientific interest, of course, and never again." The physician paused and added, "Matter of fact, it's quite likely that you're that child. Can't ever tell about these things, you know."

Tensor nodded in polite agreement and continued with his own story. "It wasn't at all bad while it was going on, because I was pretty well anesthetized from body chemicals. But the hangover was terrific."
