When You Giffle...

A drifting spaceman recounts becoming lost after a bungled Jump and encountering two naked, towheaded boys who swim through his ship's viewport and complain that his vessel is spoiling their favorite zero-gravity swimming hole. He offers them food; they summon their older brother Jim, who appears instantaneously and explains that their family lives on a psionic delta where errant jumpers sometimes arrive. Jim and his family use local psionic and practical knowledge to help the narrator locate a safe Jump and resolve the interference. The story blends comic domesticity and childlike mischief with speculative ideas about gravity balances, radiation zones, and psionic currents.
