One Sunday morning, I brought in my guitar and played a few songs for the chimpanzees. In general, they prefer the quiet—loud sounds typically are disturbing to them. So I kept it low key and strummed softly, and they seemed to enjoy their own private concert.
When Kaeley arrived, I asked her to take these pictures. She said to Tatu, “HEAR GIRL THERE?” and Tatu signed LISTEN.
