“[...] the chimps had many empty hours to fill. Time can seem endless and often cruel for caged animals.
Nim and Sally did have some diversions in their enclosure: a small television set, rarely watched; a tire swing; a basketball set; and a variety of allegedly indestructible toys. But the chimps mainly passed the time interacting with each other—grooming, cuddling, playing, chasing. When occasional squabbles erupted, their high-pitched screeches could be heard from a distance. Minutes later the couple would make up and hug. Nim was frequently seen signing “sorry” to Sally, who always forgave her close friend.
On his own, Nim spent hours flipping through the pages of old magazines, seeming particularly diverted by images of people. The magazines, which Nim tore to shreds, were swept away at the end of each day and replaced by new ones in the morning. But he did manage to keep two children's books intact—no small accomplishment. His prize possessions, they were carefully tucked away in the loft area of his cage. (WER would have appreciated Nim's affection for books.) During the day, Nim brought the books down from the loft and pored over them intently, as if studying for an exam. One was a Sesame Street book with an illustrated section on how to learn ASL. The other was in essence his personal photo album from his New York years, a battered copy of The Story of Nim: The Chimp Who Learned Language, published in 1980. In it, dozens of black-and-white photographs of Nim— with Terrace, LaFarge, Petitto, Butler, and a handful of others—tell the story of his childhood (or an idealized version of it) from his infancy to his return to Oklahoma. Nim appears dressed in little-boy clothes, doing household chores, and learning his first signs. The book ends with a photo of Nim and Mac playing together, cage-free, in Oklahoma. The accompanying text explains that Nim is a chimpanzee, not a human, which was why he had been sent back to IPS.”
