Washoe's Language of Love

Washoe was a female chimpanzee who was the first non-human to learn to communicate using American Sign Language, as part of a research experiment on animal language acquisition. Washoe learned approximately 350 words of ASL.

Kat, her caretaker  was pregnant and missed work for many weeks after she miscarried. Upon Kat's return, she decided to tell Washoe herself by signing"My baby died".
Washoe stared at her, then looked down before finally peered into Kat's eyes again and carefully signed "CRY".

Do I need another reason to love animals more than I love most people?
