question:  Why was Templin leery of the children on Tunpesh?
context: ] Nothing could have seemed pleasanter than that peaceful planet. Your memory plays traitor and boils friendship down to the status of a breakfast food testimonial. There had been no mental instability in his family for as far back as the genetic records went. He had been raised in a middle-class neighborhood and attended a local grammar school where he had achieved average grades and had given his instructors the normal amount of trouble. In high school and later in college, he was the well-balanced type, athletic, popular, hard-working. How long would it be before memories faded and all there was left of Pendleton was a page of statistics? Pendleton had been in his second year as attache on Tunpesh, a small planet with a G-type sun. The Service had stumbled across it recently and decided the system was worth diplomatic recognition of some kind, so Pendleton had been sent there. Tunpesh had been inspected and certified and approved. Or maybe the Service had slipped up, as it sometimes did, and Tunpesh had received something less than a thorough survey. And then an unscheduled freighter had put in for repairs, one of the very few ships that ever came by Tunpesh. Tunpesh had been Pendleton's second assignment. Eckert and he had been chosen to go to Tunpesh and investigate. The thin red line was practically microscopic now and Templin could feel his lashes lying gently on his cheeks. Their information on Tunpesh was limited. They knew that it had no trading concessions or armed forces and that nobody from neighboring systems seemed to know much about it or even visited it. But a staff anthropologist must have been routinely assigned to Tunpesh to furnish data and reports. Warm breezes rustled through Eckert's graying hair and tugged gently at his tunic. A few hundred yards away, a forest towered straight and slim and coolly inviting, and brilliantly colored birds whirled and fluttered in the foliage. The village started where the port left off and crawled and wound over the wooded ridges. They finally came out on the field and clustered around him and Templin.
