Gorilla reads book with 8 year old

My 8 year old CJ held up a book for the gorilla to see. The gorilla kept tapping on the glass for him to turn the page!! This lasted 10 minutes! As we were leaving, CJ went to another window, held up the book and the gorilla came and sat down in front of him. He "read" for about 5 more minutes!! A little happiness for the gorilla after a recent loss of a mother gorilla soon after delivering a preterm gorilla! CJ was super excited that he could "speak gorilla!"
