When she was just a 23-year-old grad student, Linda Koebner opened the cages of two chimps, named Doll and Swing. Freed from a laboratory, Linda was present when the two apes saw daylight for the first time in their lives. Linda helped to get them back to a normal life in the outdoors, which wasn't immediately easy for two poor creatures who had spent the first six years of their lives completely stuck in cramped metal prisons.
She worked with Doll and Swing for four years. When they were ready, Linda had to move on. The apes were released into a natural habitat and Linda wouldn't return for 18 years. She was sure that the two would have forgotten all about her by then.
But, when she paid them a visit, Doll and Swing immediately recognized their surrogate mom and the response is simply beyond words. From the moment Swing takes her hand, to the very end of the video, it's one of the most heartwarming moments we've ever seen. It really goes to show - apes or humans, we're all much closer to each other than we realize.
