I had the same experience as curator of musuem and education. I would visit the orangutangs and the older one (about my age) would come to the corner and sit with me, hand to hand (stupid glass) and chat with her eyes. Oddly, I had the same relationship with a giant grouper in the aqaquarium. He/she would spot me, swim up to the glass and ask me to "walk" with him/her. We would saunter along the length of the glass then turn and saunter back.. Thanks for triggering that memory.
